well, shit

 I marked my otherwise-new and pretty Parlec vise today, rather permanently.

I feel like I'll die mad about it, but realistically, I'll probably be over it in the morning.

EDIT:

(narrator): but he wouldn't be over it in the morning.  Before, having a machine vise which had remained un-marked, un-drilled, un-milled, made him feel special.  Now, even if he never made another mistake again, every time he looked at that mark he would be reminded of just one more way in which he is just like everyone else.  "Over it"?  He wouldn't be "over it" for years.
