For sure especially if they're friends or you know them well.It helps establish ground rules or "lines in the sand" about things not to talk about as they can be upsetting.It's even more important to let strangers know this too,as they're out of line.
Yes, its fine, but don't say it so lightly. For example don't be all robotic and be all: When you said _____ yesterday it made me feel sad. BE LIKE: Yo, what you said yesterday has been bothering me, or what you said yesterday kind of upset me, or what you said yesterday was kind of rude. It all depends on your vibe, the wording, and try not to be very uptight about it. Just say it like it is.
Yes , they should know what they have done to you , they should know they have hurt you , and they should know that you don't care either , that you will walk away from them with a smile on your face...its just another experience learn from it. And NO it doesnt matter where they are from , their race , age or colour, hurting someone is all the same , its no excuse , you hurt someone then be ready to pay the consequence. 8)
What you should ask yourself is why shouldn't you say something?
If you don't flag up things that upset you then people will never be aware and continue to act in the same manner without change, asking may also open up answers for yourself as people may act in certain ways because of something you do.
You can but sometimes, depending on whether this person is a friend or foe, telling show a sign orf weakness but if its a good friend theyll understand and probably apologize
