Tuesday is way better so far, thank you very much!
Only thing I forgot today was my phone. Well, it has solitary confinement in my locker during work hours anyway, thus, it doesn't matter.
After work, I went to the Salvation Army Store, and found three pairs of pants I can wear to work.
Now, I'll go shower, and put on something comfortable... and maybe cover my chair with some different fabric... or just veg.
