The greatest gift you can give someone is the space to be his or herself, without the threat of you leaving.
Let me refresh your memory alright? I was the one who took your bullshit. I was the one who actually cared about you. I was the one who stuck around even when everyone told me to leave. I was the one who loved you even when you gave me every reason not to. Lastly, I was the one who was there for you when no one else was. I hope you can sleep on that.
