Spaceman, Hospital Visit by Gregory Singer
The head nurse kept announcing to the dedicated staff that since they were low on masks and gloves and not sure even if they were effective, they better darn well keep washing their hands all day long, every 15 minutes if necessary.
Well, the little Spaceman was very impressed with her and her devotion to helping all people, and the spaceman felt she needed some moral support. So, he began placing his reminder signs all over the world.
In the above picture, nobody knew how the reminder sign got placed on their hospital floor. Then they noticed the spaceman at the window just before he took off to go remind others.
