Throat Heart Swallowing

My son gave me a heartattack 2 times today. Once at school, and then again at church...I say get ready to go and instead of finding him at the door he's gone...disappeared and I can't find him. At school he went out a side door, at church all the way to the car! I don't know whether to hug him or strangle him...maybe both! I'm buying a leash!
