While waiting for Valentine's Day I spent some time in creating a crossword puzzle for my SO, the activity N.39 in the page Things For LDR Couples To Do (https://www.lovingfromadistance.com/thingstodo4.html).
The website recommended for this activity (https://www.armoredpenguin.com/crossword/) is very basic, but it's efficient.
At the beginning, when i sent him the pdf file, he told me "I've never spent more than 10 minutes looking at a crossword puzzle" and I thought "I'm screwed, I didn't know that, I didn't have to do this."
Fortunately when he got trhough the questions he started enjoying it. For me it was fun to created the questions, but above all it was super fun when my SO was panicking trying to remember days and numbers, and I was watching at him on the webcam!
Ah, my mistakes with English made him laught too
So... thank you for the great idea!
