He's pissed off as he has no clean running shorts. To note: he also threw a pair away recently (I didn't know).
Until last summer, I was SAHM, did all washing. Now work 50%, still do all washing. I usually judge his sports kit washing basket by how full it is. It wasn't at "my limit" because he threw stuff away. I think he should keep track and warn me if he's got no spares. He thinks I should know and have his sports kit clean because I do the washing.
