My grandparents are upset @ me.

I was talking to my grandparents the other day. They want to leave majority of thier properties to me . They also want leave thier house to my wife and I. They said that will leave some things to my other family members. I told rather not. I not trying be rude. I just know my family. I rather not deal with tbe drama. They said that worked hard and dont understand why I am beig rude. My 👴 went to whole speech about how he fought fir this country so can leave something to his children. They raised me but my 👪 cousins aunts mom included will are well bitter vindictive and crazy. I don't like that hurt my parents though. I just don't know what to do. I hate subject but my granny sick with cancer and thier older now.
