Not to say making friends online, I feel myself rarely making friends these years. As a 30s, with limited time and energy, I can only try to well maintain the current relationship.
My mindset has also changed over years, I want to set aside more time for myself and my family. It is not saying that friends are not important any more, it is just I am tired of making new friends.
I will open to making friends online, but it is just not my style, I don't enjoy social interaction too much, a small friend group makes me more comfortable.
