It’s funny how people frequently use the line, “Always remember that I was there for you when no one else did“, because where we live in is so complex that you cannot control every possible feeling or scenario. People tend to forget that the world does not revolve around themselves. You can’t possibly think that someone is taking you for granted for someone else after all the things you did for him/her when as a matter of fact, someone out there is thinking the same about you.
It’s simply the circle of life. You cannot go out there and demand something that is beyond your limitations as a person. You can’t be seriously telling people off how they should make their decisions or threaten them for that matter.
This line simply implies that whatever deed or your so-called goodwill did is expected to be returned or that it can’t just be taken down from the Board of Debts between you and that’s a shame.
