Should you ask someone you like out?

are you friends with this person? if not, get to know them better say hi or ask them if they want to hang out.

I don't think there would be harm to that, however, as stated above, I would work on getting to know the person a little better (depending on the ALREADY relationship), otherwise if the two are friends or at least have talked for a little, go ahead and ask them out, wouldn't hurt to at least attempt.
