Mask errors in the past, of my life, I would say.
Or even leave a white solidified patch instead of correcting it at all. And I thought of how useful that would mean to me. Thoughts then trailed to the time when I was having a hard time with my family over a stupid tattoo.
And I figure I wasn't as forgiving as I thought I was.
Forget that, although I still wished there was a correction fluid in my brian right now.
