compare to/compare with

It may be a subtle difference, but there is a difference. Isn't there always?

If you're focusing only on the similarities between two things, "compare to" is the correct form. "Her dinner could best be compared to warm puke." You see, I'm showing how her dinner and puke are synonymous. I'm not even sure who "her" is. It's just an example, so calm down.

Now, if you're looking at both similarities and differences, then "compare with" is your man. "Let's see how last year's budget compares with the current one so we can make any necessary adjustments."

It's not complicated. It never is. I don't know why you insist on thinking it's more difficult than it actually is. Compared with brain surgery, this stuff is a snap.

See you tomorrow. Time to figure out what to tackle next. It's not as if I don't have enough fodder for discussion. For that, I thank you.
