I got sunshine in a bag

I have a computer science department mailbox I don't usually check, partially because it's not very convenient, but mostly because it usually just has junk from "Friends of CS" (tech companies pay money to the department for recruiting purposes).  Today I had a couple pieces of mail that were surely, from the looks of it, sent by Friends of CS.  One in particular caught my eye since it had what appeared to be a printing error on the address.  I figured it was just a form-letter that did a really good job of imitating handwriting (I'm always impressed with mass mailings that do a good job of this).

I opened the envelope and saw the following:

My first thought was that someone wanted my money.  No thank you.  On the way to the trash, I flipped it up to read the inside.

This was probably the best way to start an otherwise rough-starting week.  I don't know how long ago this letter was sent (I was the TA for this student last fall), and I'm super glad the department hadn't thrown it away (although they could have tossed the announcement about the pizza party last month).  But mostly, I'm glad this student (I removed his name so it would be anonymous) took the time to express his appreciation.  It was a small thing, but it made a big difference.

Thanks, [name removed for the sake of privacy]!
