In this positive facade

It’s pretty funny how I keep up this positive facade, when I’m all gloom inside. People whom I try to communicate my darkest and vilest thoughts eventually give up, and yet, I’m known for smiling alot.

I guess that thing people say that “those who smile a lot are the loneliest” can be quite right.

Though, would there be a difference if I say that I’m just really fond of being alone at times?
