To all those that don't empty your email's trash folder, I understand. What if 6 months from now you need something that you deleted from your inbox a year ago? Don't laugh, readers, it happens.
I was going to my Math Final on Monday and was shocked when the website that told me where to go to take it was down for servicing. I panicked. I don't have anyone in the class that I speak with regularly. Mainly, this is because the class takes place at 9 am. I mean, come on: do you open your mouth before 9 if you can avoid it? So in utter desperation, I remember that in the beginning of the year the teacher had mentioned that he had a website that mirrored the University-run url. But where was that link? I emailed it to myself on a Tuesday - last August!
So what if your email service provider tells you your trash is over 10MB and needs to be deleted. Who cares if your girlfriend (if you're lucky enough to have one) thinks you're crazy! I made it to my exam on time, proof that there is a kernel of wisdom in the mundane practice...
