I would not dream of showing up to a wedding without a gift. It's to help them out as they start a life. Why celebrate it without giving a little boost. How would you feel if it was your wedding and people showed up without gifts?
i brought a gift for a wedding I attended to 2 Saturdays ago and the mother of the bride got mad at me for not paying for my plate?! like wtffff and she told me ger daughter already has 2 coffee makers and she didn't need another one. wow! I couldn't believe my ears. her daughter had to get mad at her mother for insulting me. too much drama!
Never thought of it, but after reading the other responses, yeah I think it's better to buy a gift, but make sure to put your name on it or it will be a waste of money because the newlyweds won't know it was from you.
