Mail all hallows ie mail
A clever pun!
"Mail" and "Hallows" sound similar, don't they?
All Hallows' Eve, also known as Halloween, is a holiday celebrated on October 31st. It's a time when people dress up in costumes, trick-or-treat, and enjoy spooky decorations and activities.
So, in the spirit of the pun, I'll respond with a playful "Boo!"
