For the record, quiet people can be happy, too. So can people who don’t smile and socialize all the time.
In an “extroverted” world that never stops making noise, being quiet is a gift, not a drawback.
Introverts are not weak, nor are we pushovers — we just have to assert ourselves in a way that works for us.
My extrovert husband and I had to learn to meet in the middle — I may go to karaoke with him, but he knows not to pass me the mic.
