The most beautiful thing in life doesn't cost money, right?
A slight smile, a laugh, a slight emotion running across the face. It doesn't take much to do this, it's enough just to delve into yourself, into your thoughts and trust the interlocutor. It is enough just to delve into your body, its desires and trust it. There is always freedom for movement around. There is always a reason to prove yourself around.
It's so simple, but it shows our humanity in us. Manifests personality.
