"So nice to meet you like this."

"Like this" is the simple additive that turns an expression into something quite electrically charming and it can be equally delightful to reply.

"I’m glad you said that."

In riposte to any double meaning naughty suggestion, "I beg your pardon" should be used. "I beg your pudding" is the jocular form.

In showing enthusiasm or shock, have ready rejoinders gradually waxing in crescendo. Gosh. Holy cow. Gee winikers. Land sakes alive. And for ladies confronted by a deliberately exposed outsized engorged gentleman’s appendage from which she is not yet sure she wants to run.

"O my god."
