There are few friends that you can grow with.
After not seeing each other for, say, 5 years, it's relatively easy to just
Of course, after 5 years you will have both married
and had kids.
But when one of you had a boy and one has a girl
You can giggle and dream about them marrying someday
Or just being good friends
who sneak kisses and share toys.
It's good to have good friends.
