As a  single, I can go out as much as I want to without telling anybody what I'm doing. I can flirt with whoever I want without being monitored. I can hang out  with anyone without hurting anyone's feelings because I owe no explanations.
But after a while, it does get lonely. After a while, I wish I'd someone because everybody else around me does and I see how happy they seem. Now I wish, I could stay indoors with someone, cuddle up and watch a movie in bed instead of going out and partying every weekend because it gets old and at the end of the day, even if I had a night stand, reality sets by the day and  I still feel lonely.  

There's self love and companion love.  

I wish to evolve from the deep thought.
