Well, with all do respect you have no idea what this fella with the kids has on his plate. Maybe the kids don't have a mom, maybe the mom is sick, maybe he is just a good dad that wants to spend time with his kids. You honestly think he was having the best day? prolly not, I've been there my friend. Don't be so quick to judge.
I always have beans and beer for dinner the night before and eggs for breakfast. There are passive aggressive ways to get even, use them
