Last week, I went to Paris with my two kids, and last minute, added two of Cruzzie’s friends. Initially, I had no plans, so it was a mad dash trying to figure out what to do with four kids solo and how to make it fun for everyone. Normally, I just like to walk around all day with no real plans, but I knew that that would be harder with four kids. Thankfully, I had a dear friend who told me about an app “Flash Invaders” which helps you track the space invaders — tile mosaics all over Paris buildings made by a certain French artist, an Unidentified Free Artist that goes by Invader.
