I'm not going to go to my cousin's wedding because it's too much trouble.
So you're just going to give up on your cousin's wedding just like that because it's too much trouble?
Yes, it's too much trouble.
You should always attend your family's events. It's wrong to ditch them like that. You should be there for your cousin's wedding.
I think it's silly to have to go.
Just imagine how your cousin would feel if you didn't attend his wedding. Also think if your family abandons you on your wedding. I guess that'll give you better understanding of consequences of your decision.
