As my puzzles seem incredibly frustrating, and one was a paradox with no viable answer, here's a better one.  Based on my belief that a goodly number of people really enjoy having a go at them, trying to stimulate the gray cells, I couldn't resist.  If you don't enjoy pondering, not to worry.  But to work the brain is healthy, you'll have it longer.  (Note to  good friend:  Skip this, but take aspirin just in case lol).   

==============================================================  

I recently returned from a trip.  Today is Friday.   

I returned 3 days before the day after the day before tomorrow.  So:  what day did I return?

__ Sunday

__Monday

__Tuesday

__Wednesday

__Thursday

__Friday

__Saturday

Hint:  Examine the last sentence carefully, therein lies truth !

Hope you do well.  Cathy
