I told her I would be paying for it out of my own pocket to which she replied ...well make sandwiches instead!
You've just lost your father, she has never met you, and invites her son to whom an invitation was not given and who only saw your father once - and talks to you like that?
I think you have to put your foot down here. This is a celebration of your father's life for those who knew him well - not a party for anyone who feels like they might want to come along for the free food and drink. Because apart from that, what interest can such a gathering hold for someone who probably knows damned all about your late father?
Sometimes I'm just completely astounded at the utter pushiness and insensitivity of people. The fact is, she had no right to invite anyone without consulting you first. I'd be inclined to dis-invite her frankly, she sounds like trouble.
