It seems strange that someone needs to be blessed just because they have allergies.
For that reason, I suspect Spring is probably God's least favorite time of the year. Someone sneezes. Someone says "God Bless You." And here comes God because someone asked for him and it's just a stupid allergy.
Sometimes I wonder if praying to God too much is a little like kids calling 9-1-1 and jamming up the line. Someone else calls because they have a severed head but gets put on hold.
I guess people are just trying to be polite but they should really think about what they are doing.
This next April when you say "God Bless You" to the guy sitting next to you on the bus, you better hope there isn't a story in the paper the next day about meteor showers in London knocking down Big Ben. Totally your fault.
Saying "God Bless You" when someone sneezes . . . eh.
