the Vessello Cycle

is when one has a best friend for a couple months that turns into an enemy, then becomes best friend again multiple times over

Tim:Hey Billy youre my best friend.

Two Months later.... Tim: Screw Billy i dont care if he died.

Two Months later.... Tim: Billy where you been, I missed having my best friend around.

Billy: Sounds like you have the Vessello Cycle going here
