Yeah I do honestly get what you're saying.
It's just that if we all followed that line of thinking we could never open up about our feelings, because no matter what we feel down about, be it kids, money, work, housing, health, pets, friendships, marriage, weight, eye colour or literally anything at all, someone could then come on and tell them to consider other people's feelings.
And that's the sort of thing that can stop people opening up and getting what bothers them off their chest if you see what I mean?
I guess one person's problem is another person's trivia.
