It is so funny that you posted today about your mom not teaching you to cultivate friendships, mine was the same way.
We lived in the country and the only friend who got to come over was the girl who lived across the street. I can count on one hand the # of times that I got to have another friend come over.
So as a result of that I am just fine by myself, don't need some one to entertain me.
Not long ago I realized that my mom didn't have a best friend of her own, only casual friends and acquaintances.
I have a couple really good friends and what do we do? Talk, talk, and more talk, praying together, going out for lunch or dinner, helping each other out, etc.
I have never painted her toenails, but if you would like me to do yours I would.
