Avoiding someone will grow somebody's persistence 

why so thick faced de? D:

I am in no privy of judging whole bunch of guys........but some of guys whom i know, er.........................does that.

that type of guy reminds me of the type that once crush on me,
i used to be really active in school sports, i love volleyball and tennis,
so i play pretty much alot, but 2 my surprise he kept entering into volleyball team and tennis team, i got annoyed and quit both. Then i took basketball, he followed. i finally cant take it anymore and just told him face to face

What about an ultimatum (though sounds harsh!)?l

Keep going until they get the clear signal.

Some even more persistent, that can go for years.
