because it is fast and I get lazy writing my full name.
Sometimes when I write "TK" I accidentally hit "L" instead of "K."
Luckily I catch that before I send off the email.
I think if I did sign my name "TL" that it would be funny for two reasons:
1. I made an error.
2. My boss's last name starts with an "L" so...
that's not that funny.
In other news,
it snowed tonight, and I didn't pay attention in Physical Science except for when we wore the 3D glasses. That was "pretty cool."
