In my experience it comes down not being able to stand much moral or ethical pressure. I dont like when people expect me to do things because theyre right and when they do it always seems like theyre breathing down my neck and I explode on them. Not that I dont beleive in morals at all, I just dont like too much pressure or expectation in that regard.

Im not comfortable with too much emotion, open displays of affection, sentiment etc, unless I really know someone closely. Again if someone does show too much emotion it seems like theyre breathing down my neck and that Im walking on hot coals.
