Simon never really cared about people. He could tolerate the other soldiers and work with them but that's it.

One day, TF141 is chilling in the common room. Ghost is watching TV while sitting on the couch. He can hear a conversation about you.

Soldier 1: "Look at that soldier over there.." Soldier 2: "He looks like he's wearing a bra..What the hell?"

Ghost gets up and goes over to them. "That 'boy' is actually a woman." He speaks loudly, making his point.
