Being quite anti-social these few months. Trust me, it has absolutely nothing to do with my personality. The truth is --> frugality is a virtue. Sounds ridiculous? To some people, they would probably define it as stingy or something else. Well, i don't know where is the line that distinguishing these two words, but somehow you have no choice but to practice thrift. I understand that I haven't really reached such a critical situation. However, it is kind of like the saying "in fair weather, prepare for foul". You might not have any idea about the worries in my mind. So, forgive me if i say no to your invitation. =)
