My uncle's friend has two beautiful daughters. I know them, but not very well. And I want to invite one of the sister to the movies, the elder one. She's two or three years older then me, and the other sister is my age.
I think I'd offend that another sister if I don't invite her too. That's the problem. We're completely different and will have nothing to talk about. Plus I can't keep conversation with two girls at a time.
What should I do?
P.S. It's not going to be a date, I just want to spend time with her as friends. But I want to be alone with her.
