make faces at her
taunt her? haha, juz joking 
Hmm in my own opinions la..l feel that the gal will only be cheered
up when she is not in a good mood is only when the person that she
like or hav good feelings de is ard her accmpying her, even the
person did nthin much, keeping quiet...by accmpyin by her side is a
great comfort to the gal already
If u are those ppl that she had no feelings de or dun like u...no
matter how hard u try to cheer her up is oso no use de..
So u juz hav to ask urself...whether u tink the gal like u not lor
or did she hav any good feelings abt u?
