Q: My dad is dating a much younger woman, and I think she’s in it for the wrong reasons. Do I say something?

You should be happy for the guy. After all, old-timers like us go out of our way to eat at restaurants with flirty young waitresses. So what if they’re working for tips? 
If you must bring this up, be respectful, okay? Start with the good stuff, like her adventurous side. If you think he’s spending too much, say so, or talk about the 
differences in their likes and dislikes.

Stick to the facts, and if he’s not hearing you, let it go.
