Dd is used to swearing and sexual humour (I work in sexual health)
Yes have 2 tickets for Book of Mormon for tonight and DP refuses to come with me.
I have asked all my mates and not one will come with me 
DD really wants to come and tells me she hears the worst swearing and sexual stuff at school and she can cope with it with no issues.
However I feel like a bad parent
if I take her.
Anyone reassure me? Or is it an absolute NO
