Wah... got fighting spirit. In my dictionary, this is call si
chang lan ta. Sometimes can work one, but usually fail lar.

Come on, don't stress yourself dudette. He is not bothering you
now, so that's good. However, if your friend is being annoyed by
him, then it is up to his own discretion to avoid him. If you see
properly, it's two separate issues. The 'bothering on you' is gone,
it has shifted to else-where. And the truth is, it's easier for
your friend to avoid, get annoyed or even scold the hell out of him
because he is not exactly involved in this one-sided affair.

Cheers
