This may sound weird but I don't like being touched. When a family member puts their hand on my shoulder or stands too close to me, it makes me uncomfortable and feels weird. I am not a hugger or physical affection type of individual. I like my personal space.
Oh I'm like that too.
I used to be much worse (unannounced touching pretty much got you punched) but luckily I've managed to control that. I still don't like being touched though, not unless I give the go-ahead first
