From experience, it depends. Sometimes, getting a present and not giving one can become awkward. You don't need to get something really extravagant, just a simple, heart-felt card and/or a box of chocolates would do fine.
to show him that you love him
it depends on the person your giving it to
Valentine day, birthday, christmas, anniversery, when she is in the right mood (calm, happy)
Only if this is not your first valentine with her.
give your girlfriend/boyfriend a gift that you know by heart that he/she will like
Well does he have an email if yes write it on his email if no give him a valentine card I gave 1 to my Dad.
No because then she would think you dont know her.
A good, reasonable Valentine's Day gift idea to give your girlfriend would be a cookie cake. Another idea would be a box of chocolates and her favorite colored rose.
LOVE!
an std
give gift to your mom,dad or sister
Gifting is not a tradition associated with the valentine's day, its about loving. Anyone can do the gifting depending upon the understanding and wish between the two.
