Girls are typically easy to please. As long as you don't completely forget, you're doing well. Flowers are always good, think of the typical stuff. It may seem cliche but it's a cliche for a reason, we really do like the stuff! Flowers, chocolate, teddy bear, card....anything. Or what I usually prefer from my hubby is a nice dinner. Good luck, if you care enough to post this, I'm sure you'll please your gf. Good luck!
