I'm at the mall waiting in the line to take pictures with Santa and there's this couple behind me arguing (quietly) but I can hear. She's threatening to take the kids and he was like "oh yeah and take care of them with the $70 in your account) btw she just smacked him while I was typing... mind you they're are doing this in front of their two children. The scary thing is.. the kids don't seem bothered by it so most likely use to it.. so sad
