Let me share what happened yesterday / last night ! It was raining when I took the first load of boxes to the P.O. yesterday morning.....we had already had 2 &1/2 inches, and it was still 'drizzling'.....I had to set the stack of boxes I was carrying down , in order to open the P.O. door..... bottom box got wet on the bottom.....Post Mistress said, "Don't worry about it, I'll set it here, under the ceiling fan...and it should dry out by the time the truck comes. "....... Fast forward to 10:15 last night....... Phone rings...it's the "Hub" Post office, in a large town about 30 miles from us....."The box # "such and such", addressed to "so and so", is wet on the bottom ! What is the contents ? Is it leaking ? We see holes in the box ! Is it something alive ? Should we continue delivery ? Do you want it returned to you ?........After an explanation on my part, they said ,"OK ! It's shipping !" On the "serious side" of this....it's pretty nice to know the P.O. people are both vigilant, and concerned about what's going through the mail system, and for all the "flack" the Government and especially the P.O. Department takes, they are doing what we "pay" them for !
