Forgive my poor English but these are brilliant analogies
Meanwhile, we 毒撚 don't even have packaging since there's nothing inside anyway, or all that's left is spoiled food. So there's no point in chasing except expressing utter disdain.
Again, we 毒撚 are like spoiled furniture. Spoiled is spoiled, it is typically an irreversible process. So girls don't need to contemplate: she, or any girl, can ever be the one to change him.
Finally, for the 毒撚/kam撚 like me, stop your FF in getting a girlfriend, girls won't ever send any signals to you. Rather, create chances to practice communication, no matter with boys or girls (when chatting with girls, just treat them as boys). At first, you will definitely be the weirdo, but through trial and error and actively listening to how others handle topics, you may improve. Yes, there's never a guarantee, but at least you tried stepping out of your comfort zone. The goal is never to get a girlfriend, but just to offer ourselves some interesting life lessons.
