We all have something we are good at. We can't be the best at everything. There is a struggle of sharing what I know with people and also avoiding doing so because they probably think they know it all or don't care. I think that is something my grandpa was good at, was seeing people's strengths and knowing what each person was put on this earth to do.
I think as a family unit, it should be solid. Unfortunately, it isn't always that way. People aren't always capable of not behaving badly, so it makes life a solo thing instead of a comraderi.
