So we have all probably had situations where someone likes you and you do not like them back.  I normally never lead people on but...

I got drunk.   Twice.

Now normally this wouldn't be to much of a problem except that this is also the sister of a friend of mine and I see her a lot.   I drunkenly promised to take her out.  Which I am regretting right now.   However knowing her personality I am betting that i am just the flavor of the week and this will all blow over soon without me having to do anything.  If thats true, don't I own it to myself to get laid or does tha make me a bad person?

We are all bad people. So go ahead and ignore your restrictive ethics!

dont you dare cheat on me!

Yes.

Now, tell me the situation.

You could lose that friend if you sleep with his sister then it all blows up.

How does that make you feeel?
Seriously do you feel like a bad person?

I'm not saying you are a bad person but no you don't owe it to yourself. Playing with someone's emotions is in my opinion one of the worst things to do.

Doesn't "flavor of the week" mean that she could just be playing with his emotions?  I don't know I might be interpreting it wrong.  So isn't it more of a thing of being a bad person for taking advantage of the situation?

Just don't be drunk enough to forget to wear a condom..
