For sure...I learned that lesson as a child. Got my scissor privileges taken away a few times over it before I learned my lesson, though...
Then, one time I decided to cut my own hair when I was around 6 and after looking in the mirror
I suspended my own scissor privileges.
Took 'em to my mom and told her to lock them up, throw them away, or whatever because I never wanted to be around scissors ever again...lol
I kind of looked like this little girl for a while...until my hair grew back out.
So yeah, scissors can definitely be dangerous in many, many ways.
