Can you believe I've never brought a wedding gift before?
Do you not buy wedding gifts on purpose?
I hear it's not a good idea to give a couple gifts because I heard they break up soon.
If someone invites you to their wedding, it's expected that you bring a gift. It doesn't matter if they break up after since they are spending so much money on you to have a good time.
Idk. I think I'm doing them a favor by not getting them a gift. They should still send me a thank you card.
You seem to have given this some thought, but most people will accuse you of being rude for not bringing a wedding gift. It doesn't have to be anything expensive. It really is the thought that counts, it's a token of your respect for their love.
