It's just a hunch I'm getting, anyone else?
The replies are as blunt as to be expected on AIBU.
Something similar at my friends wedding, one of her friends (probably ex-friend by now!) turned up with her baby and said "the invitation said no kids, I didn't know that meant no babies either" 
What are some of your inconsiderate wedding guest stories?
