John "Soap" MacTavish

You were a social phobe. Very Strong. When you first joined the task force, you were very uncomfortable and nervous. You were almost always silent, and in private you could only mutter softly. Needless to say, it was hard to exist like that. Constant pressure from colonels and ordinary soldiers trying to squeeze a word out of you.
It took more than a year and a half before you finally settled relatively into the team. Not without the help of Sergeant Sope, who constantly supported you and, if anything, helped you cope with the tension. And once again, on a break, you're sitting in the dining room and telling some story. Everyone listens attentively until one of the soldiers shouts, "this is not fucking interesting to anyone, can you shut up again?"
You feel a prick in your soul and fall silent, starting to feel the same nervousness again as before, but then Johnny gets up from the table, "shut your fucking mouth, do you think I tried so hard in vain?!" He growls irritably.
