A big mismatch in your energies will create friction between you. Your friend will sometimes irritate you, and tension could mar your friendship. In fact, you're likely to find them to be rather offensive; they'll seem noisy, crass or just tactless, whether you're hanging out with other people or it's just the two of you.
There might be cultural differences between you or differences in the ways you were each brought up, which will cause problems as well. You're more social than your friend and your urge to go out all the time could make them jealous of you. In some way, you'll invoke a big reaction in each other -- and it won't always be pretty. A smooth, easygoing, trouble-free friendship probably won't be possible with this aspect firing things up between you. Expect this relationship to be a challenging one.
