If you spend too much time thinking about how to make everything equal and fair between you and your friends, you’ll end up wasting a lot of time and creating way too much work for yourself. Life is simply not fair, as difficult as that is for you to knowledge. It’s a messy affair full of selfishness and selflessness. Look at things with a farsighted view. As long as you think things are generally equitable, that should be good enough. Don’t get lost in the nickels and the dimes.
