Do you think it's wrong that my uncle and aunt didn't bring any gifts for me from their vacation?

My uncle, his wife, and his children recently traveled overseas for three weeks. They just got back, but they never even told me that they were traveling in the first place (had to find this out myself through Facebook). Nor did they bring back any souvenirs or specialty items or what not. When I traveled last year, I brought back chocolate, small trinkets, and toys for them and my little cousins. The least they could do is reciprocate, don't you think?
