I got married a few months ago in Canada. My husband and I are originally from Israel. We still have friends there and my husband's parents live there as well. In May we are having a celebratory party (not a second wedding) in Israel so that we can celebrate our marriage with my husband's parents and friends that couldn't make it to the wedding in Canada. It is a very strong tradition in Israel to gift money. My sister's mother-in-law sent us a significant amount of money when my sister came here for the wedding. I worry that if I invite her to the party in Israel she'll feel that we're looking for another gift or just feel pressure to give something just because that's what's done there. On the other hand I don't want to seem ungrateful by not inviting her. My instinct is to not invite her to the party, but to go visit her and thank her that way, I am planning to bring a small thank you gift as well, but I do worry that she'll be offended if I don't invite her. What would you do?
