I still don't understand why my almost 5 yr old messes with me. I give him everything and anything and yet he still pushes my buttons with his behavior. He has to find ways to irk the sh*t out of me. Like putting his hands in my face, screaming out loud, throwing things around or to me. It's crazy! Almost like he's trying to drive me crazy. Only with me. He's fine with everyone else. Makes me wonder if he even likes me lol
