See No Evil, Hear No Evil, Do No evil?

First of all, SHADOW, whoever you are, you're clearly a guy and you sound like a bad guy.

We need to hear more from you on a regular basis! Women need to understand why guys like you do what you do.

Or is it just the simplest truth...because you can?

Ok, so Truth raised a tricky situation most people might have been unfortunate enough to find themselves in. What to do?

Well, remember most women will always shoot the messenger.

Before you even think about doing anything, be crystal clear on what you saw. 

If you didn't see any actual wrongdoing, you could well have the wrong end of the stick. Inappropriate flirting is never ideal but its not necessarily a dealbreaker either. So if you just see a friend's beau flirting in a big way, it could just be an ego trip. I'd recommend you have a word with the beau but leave your friend out of it.

BUT, if you see some serious wrongdoing...(and in a situation like this, unless you see them having around of tonsil tennis remember, there might not be any wrongdoing) I'd dodge the bullet with the messenger's name on it and go straight to the source of trouble, i.e. the man and stick your flippin' oar right in.

1. Out him in front of his date (no guarantee she cares but if there's any chance you might burn his cables, take it!). When I say out him, ask him, where is your girlfriend? 

2. Talk to the skank (if she knew he was attached) lady if not. Wait until you can catch her alone, when he goes to get a drink or better yet, if she goes to the bathroom. Just be honest, say "If it was me I would appreciate someone telling me, he lives with someone. just thought you should know." You can't control what she'll do with that information but at least she knows.

3. Talk to him and ask him what the f*** he's doing. He might feel bad, he might not but at least its a I see you, you see me situation.

4. Tell your friend. This one is tricky as I think many women know their men have some unsavoury extracurricular activities but are quite happy to play their role. So you marching up with your 'new' information, might 

a. not really be new

b. force her out of her f***ed up comfort zone and have to at least pretend to address a situation she'd rather ignore.

Keep the conversation as brief as possible, stick to the facts and don't meander with the story.

And be super sensitive to if she wants to talk in which case do, or not, in which case leave her alone and she can call you back when and if she's ready.

And back to what Truth said, the best liars know the most effective lies are the half truths. You're not as likely to mix up the details, and by saying he saw you before you speak to her, he's effectively squashed the situation......
