I don't think it sounds cheap. Like you, I gave my daughter $10K for her wedding in 2009 and told her she could spend it on a car or wedding or whatever. Her father and I were divorced and living thousands of miles apart, so I do not know what (if anything) he contributed. But I did know that $10K was all that I could manage on my own.
She decided that her wedding out in Oregon simply had to be two weeks before my retirement day (rolling my eyes). Talk about stress!
And yes, that was the last time I ever flew in an airplane (same for Frank).
