Be My Valentine – Logic Puzzles
Freddie was in love with three girls. He couldn't decide who he wanted to give his heart to, so he sent all three a Valentine's card. But poor Freddie was out of luck, as each girl thought the card came from someone else and Freddie was left on the sideline.

Last week my wife and I found ourselves stranded on an island, oops!
Unfortunately, we were also stranded with our two sons, with no clear means of rescue.
