I was getting ready to send out invitations, so I asked my dad for a few addresses of family members. He sent me a list of fifteen extra addresses for his college friends and coworkers, some of which I have met and some I have not. I really don't want to upset my dad further because I have pretty much turned down everything he has asked for this wedding. My fiance and I are paying for the wedding ourselves. We have 125 heads in our contract, and my dad's friends would bring the total number invited to 175. This is way too much! My venue's policy if we go over our number: they will either close the doors after 125 people are let in, or they will immediately charge to a credit card we give them. I have explained this to him, but he doesn't seem to understand. He has already told these people they would be invited. Some of them I want to invite because they are family friends, but coworkers? Really? Is this normal?
