STEP 1:
- Remove hand from mouse.

STEP 2:
- (Only do this if you are having a hard time trying not to leave) Firmly grasp your hand and resist it from wanting to leave.

STEP 3:
- Sit back, and watch your teammates.

Note: if these 3 steps seem too unrealistic and unaccomplishable to you, then you might've entered an irreversible stage of the "leaving syndrome." We call this irreversible stage in the medical field: "TTV SWEATY WRAITH SYNDROME". Within nanoseconds, your bodies reflexes instantly press esc and then click on leave match. This, clearly, is not ideal.

I hope this guide helped :)
