Who am I?

For more than a week I was in Kluang, Johor with two of my friends of the same university. In the beginning, I choose to believe that this will be a chance for me to get close to the two of them. However, things went array as I expected. Staying in the same house was not a joke; it really took plenty of patience and time to maintain the relationship. Moreover, what make me more anxious was that I was not able to maintain the rapport with them as I usually will be the one silence all the time. I was not sure of the reason why i was so silence; my mind went blank every time i put myself in the social circumstance. I could not think of anything else even i had tried real hard. Conversation topic with them from me is sparse.
