WhatsApp Group and any Other Groups

Not everyone is keen to join or be included in some groups, like WhatsApp or any other groups. Me, for instance. I'm not a group person, not a people person. I prefer to have personal texts rather than group texts. It is not that I am being arrogant, I'm just not so into groups, any groups. 

Even if I join certain chat groups, it will be very specific and for something that I really cannot avoid. I do have some chat groups, that is limited to work and neighborhood. Other than that, I prefer not to join.
