Shared joy is a double joy, shared sorrow is half a sorrow

1.

Shared joy is a double joy,
shared sorrow is half a sorrow.

2.

The only way to have a friend is
to be one.

3.

A friend is, as it were, a second self.

4.

A relationship is like a house. When a light
bulb burns out you do not go and buy a
new house, you fix the light bulb.

5.

On the road
between homes of friends,
grass does not grow.
