Oh no. More rolling of eyes.
I have something I want to send to somebody upstate. I am leaving the envelope untouched for a few days before I bring it to the PO with gloved hands. But I can’t predicted what will happen to it before he gets it. What do I tell him? Spray it before opening?
spray upon receipt.
let ‘age’ for several days before opening (the envelopes aren’t usually completely sealed all the way out to the end).
Given your name I would say burn after reading.
