Anytime my friend

yea you should. That's what I do and if they are real friends then they will understand

Then tell them how you feel

your a very pretty girl so guys are going to hit on you. You just have to get use to it that's all. Many guys hit on me here too but I don't put much attention to it.

Take it as a learning experience.

Why are you getting worried?
Who are they.? And do you like any of them?

That sounds good.

Then I got no Idea how to take care of them. Google it , to see how to take care of contacts like that. cause maybe the solution that I use can discolored yours .

a bottle?
