Being alone is still taboo and mildly stigmatised. Extroverts or outgoing people would look down on an introvert or push them to step out of their comfort zone a little bit because in their heads, being alone is lonely and sad. Hence, one has to go out and surround oneself with people (even if they don't bother to genuinely ask how you are).

Certainly, there are pros and cons. However, I personally prefer being alone. Why? Because I find comfort and peace in it. How? By accepting myself and be open to my own thoughts. I don't have many friends here or do I want to -- I believe in quality over quantity as I have gone through the same old shebang of temporary friends that will eventually turn into acquaintances then strangers. I believe that you should allow yourself to be alone with your thoughts once in your life as it will help you grow by deeply knowing who you truly are and that is immensely useful, isn't it?

Whether it is Saturday night or Sunday afternoon, normally, people would go out and that's great. As for introverts, we prefer the solace of our own company. Maybe we will watch a marathon of our favourite series or read a book. What matters is we are at peace with ourselves, finally. Human nature is often difficult and complex to fathom, but to be at peace with ourselves is definitely challenging through and through -- extroverts would know as well.

Anyway, let me construct a terrible mind map or something;
