I used month or two, because that's what OP used and that seemed ridiculous. Almost like OP tried to make a meme that s/he didn't experience themselves.

But anyway, I recently found code that I wrote 15 years ago. And when looking at it actually makes me feel depressed. It looks like something I would write today so I don't think I got much better.

But yes, I do have to look over it again to understand how it works as I forgot everything.
