Let it go- the things about those you love that you don’t like so much. You may love them, but you don’t like the way they (you fill in the blank) Everybody has something they don’t like about someone they hold dear.
So if you really love them let them have their “quirks” because you have yours. Don’t try to change them and convince them that your way of thinking is the only way- your way of doing things is the RIGHT way.
Do you like it when someone tries to change things about you? Be honest now. Does it make you feel all warm and fuzzy towards them when they point out what they feel are your shortcomings?
