Just do it. For me, theres no stage/level for me to do that.
Close friends or not, doesnt matter....
If i find what shes wearin today looks good on her, i'd tell her
that she has good taste and she looks really good in that. If her
hair looks great and i like it, i'd tell her. If she looks really
cute today for no good reason but really cute, i'd tell her. If a
salesgirl looks very pretty and unique to me, i'd tell her.... she
deserves the praise, so why not. Praise with sincerity. Girls will
like it.
It's up to em to think bout other stuffs (that i like her or
somethin like that)
