My favs, depending on the context and situation of course
Hi, are you guys having a good time?
You two look like you’re up to no good. Can I join?
(after some decent banter) You seem like a really nice girl (that one stings )
Hold still, I want to take your picture so I can show Santa what I want for Christmas this year (D’awwww)
Ok some of these are indeed from the world of pick up, but still fun
