My daughter has such high standards in my opinion and I want to tell her to lower them.
Don't you think that your daughter can decide that herself?
I would prefer she find someone I like and more realistic.
It is wrong to tell your kid to lower their standards for finding a partner. You should respect their choices unless they are in danger.
Well, I don't want her to date someone that I don't know.
Your daughter can date people that you don't know, and you telling her what to do will just make sure that she never tells you anything about her love life. You need to let her figure things out for herself if she's old enough to date.
