Not that I'm a pro or something when it comes to all these 'wisdom' of becoming a man. Heh. Although I did (and still is!) spend a lot of my time hanging out with boys rather than girls. Less drama. Hah.
So yes, if you have ever killed a COCKROACH (doesn't matter what size it is since roaches has to be the most disgusting house insects!) with your bare hands, no tissue paper, no cardboard, no shoes, no slippers. Just with your hand, you automatically got leveled up in becoming a man.
Good job, Koay. You are one level up already :)
