Other People

I feel like this is just the natural losing of friends that everyone goes through in the high school to college, college to "real world". Everyone starts with the best intentions of keeping in touch, but naturally you lose friends and you're left with the friends that you have in your current area and only the best of friends from those periods in your life. They might make an attempt to maintain the relationship, but it's just not enough for you.

Is it about a relationship being broken up by external factors?

I think it's 'Heaven will keep us together' not 'help me keep us together', makes more sense why it would be right place at the wrong time.

Also it sounds like 'Distant blue skies. Some where no one can reach us'

I think the song emphasizes the progression of a relationship drifting apart and eventually ending once the final soft straw is pulled away. The song talks about how others can end things with ease "Good love, goodbye" showing closure of the relationship ending, but not acceptance.

Being left and letting the other go in a relationship is one part, but the hardest part is the acceptance and discovery that occurs after. "Never thought it would mean so much" supports the point that a "self-discovery" (if you would) period post-relationship is a large compartment of what the song talks about, how you can go through blame/ anger about what you did or didn't do during the time together, as "other people want to keep in touch" but how the relationship or people are not Other people.

i think it is the ending of a relationship where both of them agree to end it. One person may feel like this is the end and speak about it " No I don't mind It's your world why would you fake it"

To me this chorus is clearly about being famous and having to shake off people who were never your true friends but kind of pretended to be back in the day. It's actually kind of disenchanting; the whole, "We're famous now, leave us alone" vibe.
