The Revolving Door

Looking at things over the past few months it's been interesting. More and more I find myself comparing life to a revolving door.
I've noticed that friends come in and out of life like a revolving door. They are there and talking to you, then next thing you know they are gone. As soon as something (life event, tragedy, news) happens, there they are again. Obviously this isn't everyone in life, but everyone knows these people.
Life events seem to happen in the same cadence. An event occurs, you spin around and around to deal with the situation, and then when you think you've got a handle on it, something else gets thrown in and you end up spinning all over again. Take for instance my married friends. No sooner has a couple said "I Do!" and there are friends and even family asking when they will be having little ones.
At what point does the revolving door of crazy slow down or take a break?
