Here's my two cents worth - based upon my own experiences as part of a couple and as a single male:- Always be a gentleman and never, repeat, never leave the husband (significant other) out of the mix...if you are going to offer to buy drinks then include him...if you are going to ask her to dance then make sure that you either directly or, indirectly have his consent...never...never assume that anything is a given.
- Do not say, indicate, imply, suggest, or insinuate anything...always be sure that what you say and do are acceptable before you say or do it...if you have doubts then leave it in your head.
- Just because she flirts or he "makes a joke" about what your prowess might be...or...it might seem like there is chemistry...doesn't mean that there is...we are all legends in our own minds and until someone else acknowledges that legend you are just 'another guy' who still needs to prove himself.
- Jsut because a couple or a single female says, "yes, let's meet" it does not give you license...it just gives you the opportunity to prove that you are worthy or, unworthy, as you will eventually evidence yourself to be.
- This is about building relationships...many or a few, good ones and bad, real and fake...all of them guaranteed to effect someone in some way...so, if you are at your best then your chances of being asked to return as the invited guest will be better...and, in the end, that is what you are hoping for - to be asked to come back again.
In the end...treat all with whom you come in contact as you would wish to be treated and you will have, eventual, success. Do anything short of that and you too will become "that creepy guy sittin' over there on the bar stool whining about how he don't get no play."
That's my two cents...I'm outta' here...
