i wouldnt ask it in that way.... remember it's not what you say it's how you say it!
There's a big difference between:
"Are you going somewhere on Valentines day"
and
"Let's go catch a movie/grab a drink/go minigolfin/go clubbing/go skinny dipping/etc on the 14th"
or something like that... when the word valentines day comes up .... yes ALL THE AFCs break loose!
Ive actually gone out wid one on valentines day 2 years ago becasue i played it dumb and ddnt know it was valentines day.... however that was during the AFCist times and i was still learning the ropes...
Still am now but i have a better grip on them
BUt yeah ... as PRMoon said, if it's a girl urr currently dating then yeah go ask her to come out... if not... then ii would best advise you to avoid asking anyone out for valentines day as it's just an overrated day where there is too much emphasis on giving crap because of this hersheys and hallmark holiday
