Be careful who you trust.

Or at least, it should have been that way.
Now it's just coming back to bite me in the ass.

Weeeeelll, once bitten, twice shy.
Friends are few, acquaintances are many.

It's not the friends you should worry about because it takes more than a simple 'I-see-you-everyday' and a 'are you okay' to be a real friend.

It's the acquaintances you need to sort out.

And be extra careful.
