We were watching a news story about a Whale that had been spotted somewhere it had no business being and then they turned to a young kid who had witnessed it and said something about “12 year old Max is worried”. They then went on to interview Max.
DH threw a cushion at the TV and told Max to shut up 
I told him to stop it so he shouted “fucking Max and his importance” 
anyway he’s gone on about it ever since, keeps telling people about it (always exagurates it) and everytime something is on the news he shouts “but what would Max think??” And often throws a cushion. He won’t say why it’s annoyed him so much but won’t stop going on about it. AIBU to think ok it was a bit of an over reaction at the time and now he’s just being weird and should forget about it?
