It all comes from my wife and her family. My immediate family is everyone gets a book or two and have a relaxing day of drinking coffee and relaxing. If there is a bigger event it is appetizers and desserts and low key.
Wifes family on the other hand goes all out, everyone gets gifts etc. So I have to live with someone who is constantly going "oh, we have to get this person something". They question of "why?" doesn't go over well.
Anyways, it'll be over soon enough then I can get back to my normal low key life.
