Very bluntly and to my face. No dropping hints because my dense arse won't pick them up, no anonymous confessions leaving me confused and wondering, no beating around the bush and for the love of anything holy enough none of that acting interested and then distant bullshit. I don't chase, period.

Be prepared for a "lol, good joke" reply, though. I wouldn't believe anyone who said something like that because I have been tricked before and can't tell genuine interest apart from a ruse.
