Make it special.

让你们的友情与众不同。

 

We are all special cases.——Albert Camus

 

The greatest friendships have quirks and qualities that are exclusive to them.

 

Search for a special activity, gesture, or saying that is reserved for your true friend only.

 

That could be a song you belt out on every car ride, a goofy handshake or gesture that no one else understands, or a weekly ritual just for the two of you.
