Waiting for the mail!

As subject states, waiting for the mail.
Some paper pet bedding, replacement air pod ear tips, my shoulder bag strap pad and some personal items come in today in the mail.
As well as some very important household paper-mail but that is through a different courier.
I've always felt the time between the annoucment of mail arriving on any given day and actually arriving to be a very liminal time, isn't it?
