I'm not going to a friends wedding
Why would you avoid a friend's wedding?
I don't like that type of ritual.
I understand that weddings aren't for everyone.  However, your friend will probably be pretty upset if you miss such an important day!
I really don't care. I can't do something I don't like.
But don't you think it's important to sacrifice a little bit of time for our friends, especially with big events like a wedding? You never know, you might just have a good time as well!
