If you knew your neighbor was cheating would you tell the husband (or wife) about it?

No, I would blackmail them into joining me for pleasure sessions.

Heavens no that is none of my business what my neighbor does as long it doesn't involve hurting children or animals.

No. It's none of my business.

No... not my place to intervene

That's a tough one. What would be my motivation? If I really care about their well being as a couple, and as friends, and I know for a fact cheating is taking place, I would try discussing it with the party doing the cheating.

At the end of the day, it is not my place to apply my own set of morals.

probably not - it's not my business. besides maybe it's not cheating; could be swingers or open marriage or such

No I don't mind other people's business

No it is their business. Not mine.

No.I got caught having sex with a guy by his wife.Messy fall out for them.

I would likely discuss it with them first, if I knew and was not just guessing. They may have an agreement that it was ok. If they were cheating, would advise them that they needed to discuss it with their spouse.

Cheating is wrong. Besides, who knows, maybe their spouse would like to play a bit too ;-)

None of my business.
For all you know, the other person probably has their suspicions.

no. especially if she was cheating with me

anythinggoes4 no matter how close I was no I would say nothing none of my concern

my neighbors were swingers

No. She figured it out after a while and dumped him.

beats me... if i have pictures.. i'd send them to their spouse and secret lover.

:D

Yeah. because don't you some times score revenge sex
