On-stair altercation

I felt so confident when I shouted up to Andy that there was a pile of his stuff at the bottom of the stairs. 

Annoyingly though, he went through the pile going "mine, mine, not mine, mine, not mine, not mine, mine...etc."  Turns out "not mine" meant George's. Which meant he had to get involved with picking up some of the stuff. 

Which, in turn, led to the on-stair altercation. 

It was one of those times you feel their hearts aren't really in it, that they're just doing it to mess with your head.
