I feel that this is a pet peeve that is also an innocent one. A lot of people give advice because they believe they are offering support and help or even as a way to offer friendship rather than from a judgmental stance. There are people who do it in a mean way, but I think for the most part it comes from the heart.

I'm a person who likes to chime in on my own experiences or how I've dealt with situations, but like you I've learned that not everyone appreciates it. So usually, if I give advice, it's because they ask for it.
