[ Singles & Dating ] Open Question : PLEASE HELP. How do I tell my parents about my boyfriend?

A guy from my school has recently asked me out, and I said yes. We're going out in a couple days, and I need to tell my mom about it. She's told me that she doesn't mind if I date anyone at my age (not going to give it out), but I'm afraid she'll freak out/ask a lot of unnecessary questions I won't be able to answer. Please help me?
