Do you still get upset?

If the comment was from a stranger (bumping into someone in the supermarket or a rude shop assistant for example) I would tend to get more angry than upset and stew on the many Oscar Wildesque retorts I could have made at the time.

If it was from someone closer to home such as a work colleague or neighbour, with whom I usually had a good relationship, I would ask them what I had done to upset them and try to sort out any problems.

If it was from a family member, especially my son, I would be absolutely mortified and deeply hurt to the point of tears and wanting to hide away.

Either way, I think there are very few people who can genuinely ignore or laugh off rude or hurtful comments.

In situations when someone has behaved in a way that I do not like, I always try to say to myself ..... this may not be about me; I do not know what else is going on in that person's life.

Someone close to me or knows me wouldn’t usually say something rude or be unpleasant. If a complete stranger was that’s different I would tell them how very rude they are. I worked with the public for years and grew thick skin quickly.

As Monica posts it depends what the event was I don’t have friends or family that would be unpleasant to me in public. As for the very odd occasion if it is someone unknown to me again it depends on the situation. If I do something wrong I will immediately apologise but if not the thought up yours goes through my head. I am not responsible for other peoples actions.

Your post is very vague. can you give an example about what you mean. I suspect you have a specific event in mind

Generally if someone was rude and unpleasant to me in public how I responded would be determined by who it was.

If it was some one emotionally close to me - partner, child, close friend and we were out together - yes, it would be upsetting.

If it was someone unknown to me, who perhaps I accidentally bumped in to, - and had apologised and they turned to me and they said smething to me like 'stupid cow'. I would be amused.

Yes I am very thin skinned,and get hurt very easily,which makes me very aware when speaking/ writing to others how easy it is to maybe without intention inflict pain.

If you are a sensitive person, any unpleasantness affects you. It doesn't seem to be possible to develop a thick skin. You learn not to show it, so the other person doesn't have the satisfaction of knowing they upset you.

Yes.
I still get deeply hurt if forgotten for some event, or from a particularly cutting throwaway line…
I wish too I didn’t have such thin skin, but am very, very careful not to let it show.
