Lol, some of us here have learned some things the hard way.
When we first undertake to improve ourselves we think that those closest to us should share in the joy of us taking risks. Truthfully, we fine out, it rarely works out that way.
Yes, or parents love us desperately and would never betray us, but sisters and friends are another story. Inevitably, they tell THEIR spouses or friends.
Then your circle, whatever it is, knows.
In the end though, im a strong confident guy (i dont mean im arrogant just that i own my decisions) and I see changing my circumstances as a part of life for any strong guy.
In retrospect i wouldnt tell ANYONE but if anyone asks now, i act like any reasonable intelligent person would improve themselves like i did and act like im proud of myself.
Trust me, no insecure little sadistic weasel (the gossipers youre talking about) will have the slightest interest in bothering you after that.
You've looked them in the eye and proven you're a better person and that theyre a sniveling little twit.
...as for random strangers who boldly might ask "did you have some work done" (this has happened to me a couple times) I like to play dumb and ask "WHY, did YOU have some done? Is that why you seem to know so much about it"?
They scurry away like little rats.
