An Urgent Phone Call

On bursting into his bedroom quite breathless he found his informant was quite correct. His wife was in bed with someone he had never seen before.

However, far from being angry, he greeted them both with a smile and a few hours later brought them both breakfast in bed.

What is the explanation for this odd behavior?

His wife had just given birth.

The Case of the Missing Matchstick

Chuck and Ruby were going to meet at a hotel for their anniversary dinner, but Ruby didn’t show. Chuck was angry and left her a passive aggressive message on their kitchen table in the form of fifteen matchsticks spelling “hotel” and went to bed. When Ruby got home and saw the matchsticks, she removed one and went to bed. When Chuck woke up the next morning and saw Ruby’s new message, he realized his mistake. Which stick did Ruby remove and what was the new message?

Matchsticks

Ruby had removed the top of the T and the new message could be seen upside down from where Chuck sat at his breakfast of sadness and anger. What he saw was 7 3 1 0 4, or 7/31/04, the date of their anniversary. In his excitement, Chuck had gone to the restaurant a day early, on July 30th. All was forgiven by both parties and Chuck and Ruby had a wonderful dinner together. They also promised to buy a whiteboard for the kitchen so they wouldn’t have to use matchstick messages ever again.

NDOLA

What does “NDOLA, PAMODZI” mean?

Thanks to the comments, it doesn’t mean anything per se, but it’s a location in Zambia. If that’s all it is, it’s not really a brain teaser, but since we’ve already worked on it, I’m marking it as solved leaving it up for posterity.

Below are former attempts to solve it.

I have yet to figure this one out. NDOLA could mean And lo, or An old, among other things. Pamodzi on the other hand didn’t have any particularly meaningful anagrams. Both words together had over 1,000 anagrams.

I haven’t come up with any other possible meanings.
