Again there are generally no problems if this
is initiated by the guy as long as it is in passing, light hearted and not
about swinging with them. Be prepared to leave them to it again. Although
you are leaving them you are earning brownie points for being a decent guy.
Don't push your luck though. If the couple are interested they WILL be back.
The chase is all part of the fun for couples as they are in control. If
they have approached you it generally means they are interested and the
conversation will quickly move to what they are after. Remember they will
tell you, don't try and push it.
