Relationship Timeline

Men and women view relationships differently.  I asked a male co-worker recently if he was in a serious relationship.  

He said, "Define serious."  

It is pretty tough to define. 

After much deliberation, I came up with timelines to show how relationships progress from first meeting to total intimacy. 

Nurse's Note: Each sex has its own timeline.  Sometimes the timelines converge, sometimes they part abruptly.

Day 0

Day 3

Around this point, the timelines diverge...

They continue to run separately...

...merging occasionally. 

The timeline splits again...

...but rejoins at the toilet. 

That's the answer.  If you can use the toilet in front of someone, it's definitely a serious relationship.
