Hey, Sweet post,. Yes, it is a very interesting subject. People are very unique its truly amazing,. when you take into account, not just personalities or character types, but then, gifts, talents, upbringing , family, culture, language ,geographical region, country, faith, all that and much more, are components that build/develop a person.. making everyone one you meet, relational/ similar to some or much extent but then so very unique and different in other respects. It is amazing.
