Eww! Someone comes at me with a dangerous implement like a pair of shears has a high chance of ending up eating it, pointy end first...
I'm off the mindset that is prone to leaving lasting injuries (psychological preferable). The last two people to piss me off:
1) Stripped 22 years of pride in 10 min.
2) Beat his ass with style. Next time he ran into me was firmly in the submissive mode.
