One of the things I do is give advice. Sometimes I give advice when people don’t even ask for it, I just start explaining things. Sometimes I’ll talk too much trying to explain my advice when they don’t particularly care or they already understand it and I end up annoying them. Learning what annoys people is a never ending process. It can be talking too much, how you explain your advice, or what subject it is on.
While it may be a way of expressing you care, you still need to be mindful of how others take it. And that can be hard.
