if you send me something on the 8th which has a deadline of the 11th and get a reply that i won't be back in the office until the 10th, but you can contact my co-worker for urgent or time-sensitive requests, why would you wait until the 15th to make sure i got it? would you not just go ahead and send it to said co-worker? have you ever been on vacation for more than a day? do you really think that your stuff is #1 priority for me to get to as soon as i return from my week long vacation? sure, i should have gotten to it before the 15th. but considering the 12th and the 13th were weekend days, the soonest i could have gotten to it would be the 11th, at which point it's still pretty much too late for everything you've already sent me.

use your brain next time. stupidity on your part does not constitute panic on my part.
