I lost Koby

It was the most terrifying thing that has ever happened. Period. I never thought it would happen to me.
I went to the bathroom,to pee. IN the approximately minute it took for me to pee...he was gone.
I walked through the living room. Saw Koby sitting on the coffee table watching High school musical 2. Glanced at the door and made sure Chris had locked it when he left.It was locked.I continued down the hallway, through my bedroom and into my bathroom, I turned the light on, pulled my pants down, remember thinking as I sat, oh this is my favorite song on HSM2,peed, and pulled my pants up and flushed. I went back through my room, up the hallway, and PANIC! The front door was wide Open. I looked to the left through the living room No Koby,PANIC! I looked to see if Chris's car was there, thinking he must have come in for lunch or something, it wasn't there. PANIC! How did the door get open and how didn't I hear it? It squeeks a little bit so I should have heard it...OMG PANIC! I walk out the door thinking he will be on the porch, in the yard, or the driveway, I mean it couldn't have been more than a minute or two, he couldn't have gotten too far. He isn't on the porch,PANIC! He isn't in the front yard, PANIC, he isn't isn't the driveway,OMG! I start SCREAMING his name running around the block and I don't see him at all! He is GONE! I start thinking someone had to take him because why else would he be so far away? I call Chris PANICKING and tell him to get home ASAP because I can't find Koby. He hangs up and is on his way, I am now shaking uncontrollably. I run down the street the other way, but with no shoes on, I decide I better get in the car and call the police. I run back down to my house, my heart is beating out of my chest, tears are involuntarily running down my face. Still shaking I reach inside the door to my purse and grab my keys. I grab my phone again, to call the police.Wait, I decide I better just double check inside that he isn't hiding anywhere.I run through my house screaming for Koby, NOTHING. So I run back outside with keys and phone in hand, and head for my car. Just as I am about to open the door,and call the police, I see something,WAY WAY down the street running back towards me. I run out into the street, sayin' PLEASE GOD LET THIS BE KOBY! I squint and take a few steps forward shielding my eyes from the sun.I can't tell if it's a do or a person, or what?THEN I see IT! His little bare feet, and pajama clad body running fast towards me, yelling Mama, and laughing...I literally can't move for a second. I realize at this point how panicked I was! I then RUN after him and my mind is racing. Do I hug him, spank him, yell at him, or kiss him.I think I did all of the above. I carry him back home the whole time, thanking God for letting him come back.Chris calls to see if I had found him yet. I tell him I did, and he is of course upset with me for losing him, and I am upset enough without his fear filled words crashing down on me. I held Koby for a minute but I seriously thought I was going to have a heart attack or pass out as I couldn't stop shaking and I could hear my heart beating LOUDLY in my ears. So I put him in his room, with some toys and a video, for a minute.It is his nap time anyway. And I just want to keep him where I KNOW he is safe, for a MINUTE!
It has been about an hour since this happened.It seems surreal. I am still shaking horribly. I can't catch my breath,and I feel like the worst mother ever. It was honestly the most horrible experience of my life! I pray NO ONE ever has to go through this! My house is soon to be laden with Ft. Knox type locks, alarms and security to ensure we NEVER go through this again! Terrifying. I thought I had checked everything. I thought he knew better. I thought he was safe. All in a FLASH I could have lost EVERYTHING! EVERYTHING.
