mathematical relationships

A rel B
B rel C
then A rel C

rel could be equality or greater than or less than
The first two sentences are true then the third is true

However if rel = like or get along then third sentence is not true e.g.

A get along with B (great friends)
B gets along with C (BFF)

This does not mean A and C will be friends or will get along well.

So much for relational mechanics
