There is nothing better than the hours following a lovely coffee (or tea, or whatever) out with a friend, especially if it was their turn to treat you. Being treated is the best feeling in the world, next to treating somebody else.
Some people just don't "get" the yumminess of the treating system, and never remember to reciprocate, or never allow anyone else to buy. Others get way too worried about who's turn it is.
But for those of us who love to treat and be treated, we understand, implicitly that sometimes we will treat, and sometimes we will be treated, but it will always work out in the end. A perfect friendship pairing is two of this type of people. It puts a glow on the day. Especially when every second song in the coffeeshop is The Best '80s Song Ever, and spring is in the air.
