What is fling to you?
It is like luxury goods. You don't need it to survive but you WANT it. It's not the necessity of life but it's always nice to own one or more than one. When you lose it, you won't feel the pain or being hurt. Maybe a bit empty but you would get over it very very soon.
Could you manage to be emotional dettached?
To be honest, I have to be extra careful.
