We all live in dimensions. Having friends in others makes our life richer.

We live a life.
We’re all in a dimension.
When we spend time with people on a similar dimension, we comfort us on it. 
That’s important to do it. Human is a social animal.
When responding time with people on different dimensions, we visit these different dimensions. 
This is even more important. 
It makes life richer. A lot richer.
It’s tasting different lives, diving into them.

It’s also challenge our dimension choice. The “what if I would have done things differently” question comes.
This question is disagreeable sometimes because we feel it would have been better than choosing our current dimension.


But isn’t it a good sanity check?
