There's this girl I really want to like....?

So there's a girl I want to like, I really do! I know she's crushing on me hard, and we've set up a date, but the prob is she has like a speech impedement thing. Don't think I'm like a bad person, but I'm finding it hard to listen to her. How do I get past it? I'm Really worried I'll just slay her our first date and then blow her off.
