Can not find it

I need to recharge my cell phone because it was low battery already but I can not find it. I know that few hours ago I was using my cell phone in the car while I was waiting for my son in the school. I looked every where in the house but nothing so I went to checked my car and still nothing. I called my husband at work and asked him to call my phone because I do not know my number but he was busy putting the Hinkley lighting. I waited for few minutes until he call my phone but never hear any ringing in the house so I went to checked my car again and I finally heard the ringing. I found it under the car seat of my daughter. It was funny that I never found it the first time I was looking for it.
