Ruler of the Office Essentials

Scissors, you are being divisive. 

Explanation: A ruler is a tool to measure things but also is a term for a leader, i.e. the one in charge.

Text:
S: Why is he in charge? He just measures things.
P: He's our ruler.
R: *existing* 

The Sad Side of Safety

Safety third! Because if safety is first, you won't ever do anything.
I can't think of a reason to run with open scissors, you really should at least close them before sprinting away. But really you shouldn't run at all. Or if you need to hurry, use a pocket knife sort of thing so you can safely fold away the sharp edges.

Scissors: No one will be my running buddy.
Fire: No one will play with me.
