You did good, ok? If you're friend doesn't like it then next time she gets drunk in TJ leave her ass there and go home. I'm sure she'll learn to appreciate what you did for her.
Don't worry about what her and her friends think.. Don't take her with you anymore ... And if you do like Rnger says. Leave .." I'd tell her too. Hey lame you can't hang so watch what you drink cause we're leaving you so you can find out what mexico is really like "
