Am I wrong to feel this way?

Going to start this by saying I’m in NO way ungrateful, I’m thankful for each and everything I have received this wonderful holiday.

My family has always split holidays (my parents are still together), my dads side celebrates on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and my moms side of the family on Christmas Day. I make sure I always ask who’s going to be there so NOBODY is left without something to open, my cousin always shows up to Christmas with only a select few people are gift (not even the kids) and it always bothers me, I feel if you can’t afford to give everyone a gift you should at least save the few you did get gifts for to give later instead of in front of everyone else, they always get multiple gifts and flaunt how they got their kids new phones or game systems but never show up with people gifts besides their favorites and it really annoys me. I don’t care I didn’t get a gift, it just annoys me that they just pick and choose. Am I wrong?
