But the host has NOT extended an invitation. He is FB friends with OP so if his dad did talk to him, then he should have called or messaged OP. I would never take an invitation that came from a conversation with anyone other than the host. And the guilt tripping of OP..oh your dad is old and wants to see his family..that's just wrong . OP has a job, a home, kids that come first with her time and energy. Even if she had been invited (and I really do not think she was) she is under absolutely no obligation to cart her father around to whatever he wants to do. Now that my dad can't drive and my step mother shouldn't, my sister is being gracious to supply rides for appointments and shopping, but step mom is expecting to do things when my sister has to work and actually told my step brother, who offered to take her shopping no, because she wanted my sister to do it but got upset when my sister couldn't do it when she wanted her to. Yes, it is nice for us to take care of our elderly parents, I know this summer has been a wash as that is what I have done, but when you are expected to jump when they snap their fingers because they want to do something, well, no, that is entitled SS behavior and age doesn't give you a pass over decent behavior. The only reason OP's dad is pushing for OP to be invited is so he has a ride IMO.
