If you want to forget something or someone, never hate it, or never hate him/her. Everything and everyone you hate is engraved upon your heart; if you want to let go of something, if you want to forget, you cannot hate.
Before I met him, I would dance in the shower. When he was in my life, I would think about showering with him. After he left, I would sit on the ground in the shower and cry. When I got over him, I showered so quickly, there was no time for dancing, fantasies and tears. Someone can invade the smallest part of your life, you won’t even realise it until you dance in the shower again and wonder why you ever stopped.
