Not that easy for ppl to be famous le, funnysnow. The OP might want to generate some curiosity amongst members here abt her 'mysterious' letter but we are all not that dumb dumb mah. We asked her questions which she didn't reply so.......
I donno who the OP is so my opinion is objective ah.
There are girls who try so dang hard to attract attention from the opp sex and who thinks the more guys who are keen to befriend them = their being popular. What these girls do not realise is that in playing with the feelings of guys, they will get all kinds of unwanted attention that they cannot handle. It's all fun for the girls but not for the guys, that's for sure. Some of those being taken for a ride by these girls might just withdraw and feel pai seh but some might feel so angry they want to hit back. Writing a nasty, threatening letter is just one way. Stalking is another. Midnight calls.... and so on and so forth.
IF the OP is playing such a game, then the letter might wake her up to her immature ventures to popularity. :notimpressed2: |
