Clingy friends/guy friends

Alright, here's the deal...<br><br>I love my friends to death, but some of them get a little to clingy. One of my friends is always by my side, and I mean ALWAYS! Sometimes she's not that bad, but other time's I wanna turn around and slap her! :x makes me angry that I ask her to back off for a while (in a nice manner) but she takes it offensively.<br><br>And then there's Zach. One of my best guy friends ever, but lately he's been a little to clingy. He finally figured out who likes me, and he (Zach) is also practicallty in love with me, but refuses to admit it. Now he's all of a sudden uber protective of me because he doesn't want me to get hurt by another guy. HELP MEH!
