Am I obligated to invite Grandma to my graduation ceremony?
I am graduating from College in a few months, and I only have 6 tickets. I have given one each to my boyfriend, sister, mom, dad and my Grandma (mom's mom) however I have a friend flying in for the ceremony and my Dad says I am obligated to give the 6th ticket to his mother instead of this friend. Am I? Grandma doesn't spend any time with me or my sister, has never supported our school efforts in anyway and we rarely talk.
