It has taken me this long to think "Wait, I could sue!"
Of course I won't, while I think tort reform is a bullshit platform designed to protect corporations that do REAL harm, this incident was entirely my fault. Do not switch on electric mixer blade while your finger is next to it is something that the instruction manual shouldn't have to say.
But still, an an American, suing SHOULD be my first impulse, right? It should go "My finger! I should sue! I wonder if I need medical attention."
