you say "Happy birthday!" or "Merry Christmas!" or whatever he's getting the present for. say you hope he likes it!
I believe the best present for a girl to give a boy is to let him know that you love him and care about him in your own special way.
he farted
선물을 주고 싶어 = I want to give you a present
a scarf
i would say present because it is more formal the give
If a boy asks you that then say what you really like about him. if you don't know then say 'give me some more time'.
a drawing
well depending if the child has a game system. i say video game. or if alreday has video games ask him what he wants or just give him money
You would say Thank You because it is polite and shows respect.
Thankyou, now it's your turn.
This really depends on what your boy friend likes. Get him what HE likes.
If you get on before him, give it to the driver and say that this is for the boy at this address, but make sure to tell him not to tell the boy.
