Why aren't there many geese here?
Well, I tend to make friends with people like me. People that do the same things as me and are interested in the same things as me. That's just how things work. Isn't that how you work? Aren't your friends mostly geese?
So I brought my friends, who are mostly ducks. So here we have mostly ducks. Most of the other people who were interested enough to come were also ducks, who brought mostly other ducks. Ducks share the same interests as ducks.
The question is, then, why didn't you bring any geese?
You came alone then blamed me for .. what.. not bringing your friends?
Why were you interested and your friends weren't?
You asked me a question you would be the expert at answering.
