White dude, single, here. I have no friends at all, and I discovered a valid reason for the why. Maybe you are living something similar, so keep reading.
White people are more introspective, intelligent, and stay at home more than black people, brown people and asian people.
I have two 'friends' ('neighbour friendship'), which are white ladies (they look like pic related), neighbours of mine, and they stay a lot at home, never come after me to invite me for things, (one of them already went to my home, because me and my family invited, in some occasions), still, the two of them mostly always treat me good, stay interested in my talk, and seem mostly always joyful with the idea of participating in events, or things, with me in the near future, even though these things almost certainly will not happen at all, for the lack of motivation and effort from me and them.
Me, and them, live in a city full of black and brown people, with a minority of white people. Black and brown people, which like funk music, are outgoing, like attending sports arenas where violence often happens, have poor jobs, like beer and alcohol, and have black culture in general. These things annoys me mostly, because it's not in my white race dna, neither in my two white ladies friends' dna, but we live among it. Also annoys me the fact that the males of these brown and black people are engaging in relationships with most of the remaining single white ladies of my city, but these white ladies don't seem happy at all having these interracial relationships.
To summarize it all, white people are more introverted, they only like white people, they stay a lot at home, so, it's hard for white people to get friends, even if it is becoming friends with white people. This does not mean white people, or white girls, don't want to be friends with you, white dude. It means white people have a natural difficult in becoming friends with anyone at all....... And we, white race people, have to deal with it.
