Thanks for the birthday wishes, everyone.
I am so exhausted that I gave up and asked my boss if I could take half a day of PTO. He actually said yes and not to worry about the customer for now! I said it was my birthday and wanted to have the rest of the day to myself. Now I'm just browsing some sites and buying some things with the digital gift cards I got as gifts.
One thing I bought so far was a Garmin GPS watch in a pretty blue color. It doesn't match the color of the bike I'll be getting (as it's orange), but it'll coincidentally match my pretty blue gloves I got yesterday. It also keeps track of heart rate like my old Fitbit.
Oh, and I got some stuff in the mail today gifted from me to me! I got the equivalent of under armour heat gear, but from a local company that makes them for a lot less money, so that's nice. They were on sale and I used a birthday coupon.
