^ pretty much this.

i was invited to my girlfriends friends wedding ages ago, to which i've 'officially' replied and said yes. but now one of my best mates has decided to have his stag do on the same day. so i'm going to say i cant go to the wedding, however she seems to think that this is horrifically rude and embarassing.

so, do you think its rude? and i'm not talking about rude in 1893, i'm talking about in two thousand and great.

you decide.
