First time confessing your love to the girl better face to face,
even though it may be quite awkward, it really shows your
sincerity. Using SMS will only make the girl think you're
coward...
( though most girls don't realise that guys are coward in this
aspect because they are scared of losing the girl even as
friends...if you tell them you like them when they don't like you,
they give you the shi.ttiest [piangz, stop cencoring my words can or
not?] response)
but when go steady le, no harm conveying your loves through SMS
mah...just a simple 'love u dear, have a sweet dream' everynight is
enough to let your gf know you're thinking of her.
