Haaa. Okay. There are a lot actually, but I wouldn't want to list it out here.
Sincerity. I'm sensitive to sincerity. I tend to hate it when people do things without sincerity. How do I detect insincere people? By their intentions and actions. It affects me much, because I often do things with my willingness and I put almost all my sincereness in it. When that sincerity isn't there, I won't start a thing! So, the presence of sincerity is very very very important in my life. Okie? =)
