Touch with Permission Only
Here is a personal rant I must get out before I explode.
I consider myself to be a loving and affectionate person and would typically invite the touch of another person as long as it is appropriate.
I have a much older, married, male coworker that insists on hugging several of the female employees before he leaves. Call me old fashioned but even hugs are special. If there's something to celebrate that MAY be a reason to hug, thanks for something nice hug away! If you're a man other than my husband or father leaving is not a reason to hug. Leaving forever...maybe.
My advice is this: men should refrain from touching females in any way other than a handshake if there is no appropriate reason or personal relationship. Trust me, if a woman wants a damn hug she'll initiate it.
