This is the word game where the second word of the word pair to which you are responding has to be the first word of the word pair you add. So a correct response has to begin with the word "problems...." This is why I responded to "problem solving" with "solving problems." People who post in this game have to be mindful that their second word has to be an appropriate first word for a new word pair, and "solving" is very limited as a first word in a two-word phrase. This thread has almost died a number of times for this reason.
(The other word game, Two Words With A Twist, permits you to use either word and in any order.)
I think the best idea is to play some games. I'm staying home for 20 days already.. I'm about to go completely mad. Any games are better than nothing .
