We are attending and engagement party of DHs sister (not particularly close). We can't attend the wedding as it's overseas and we can't afford to take all 5 (DH, 3DCs, me) of us. Money is tight as it is, only I am currently working although people don't know this.
AIBU to not bring a gift? We really can't afford $100 gift at the moment but I could use my savings or do more surveys at night to earn it. I'm not sure, we really don't have much to do with the couple other than the odd bbq twice a year and it's a lot of money to us.
Just for context, we have never received anything from them and engagement party is BYO at their place. Thank you.
