Sometimes being a HSP can seem like a curse. Just little chores can seem like ordeals. I had to mail a couple of packages, and I went to the USPS website to see if I could figure out what to do (since I'm highly sensitive to a postal worker frowning disapproval at me!). Yes, it bugged me and exasperated me to see "addressing and labeling" instructions on preparing a package for shipment which specifically stated to use capital letters and to not use commas or periods when the illustration right beside the instructions had--you guessed it--a period, a comma, and lowercase letters! (Close enough for government work, as they say. It will likely get there either way.)
All's well that ends well, though. The lady at the post office had a sweet demeanor, and she sent my packages on their way.
