Make new friends. Politely decline their offers to go out, if their asking. They'll get the message that you don't want to hang out with them anymore
Be careful who you trust and who you choose to be around.
Don't make friends with bad people, in the first place.
You should listen what they talk.
I have never used it. I'm not even sure what its use is.
I dont its always been that "wonder what goes on there" thing for me :D
No, it's against the law in most countries.
Only in Hyderabad.
I use Tumblr, but only as a every-once-in-a-while kind of thing. I feel like Tumblr is really only set for a certain type of person. If you're that kind of person - great! I'm not really, but I do love the funny posts and photos that go up there hehehe
God does not exist.
I did have a Tumblr account but I never use it. Best of luck to you!
