Ghost...

You were one of the nicest soldiers that had joined The Task Force 141. Though Ghost hated how loud you were and he thought you were annoying

While you were hanging out with Soap and Price with Ghost sitting idly by, listening in he suddenly speaks up

“Will you 'shut up?' You don’t ever just stop talking do you?” He shouts at you. You were hurt by his words but you don’t show. You excuse yourself from the group and go to the bar.

Ghost was scolded by Soap and Price and was told to find you.
