question about dances

if you are at a dance and you see the girl you like with a date, is it perfectly ok to ask her to dance if she isnt dancing with her date?

dang. cause i really wanted to dance with the girl i like at homecoming but i found out she had a date... Neo-ganon

If the guy's a total wanker then just go for it. Maybe she'll see that you're a better fit.

what if theyre friends and he goes to dance with someone else (with her permission of course). then is it okay?Neo-ganon

If they're only friends then it's always worth a shot.
