It is my professional opinion that two-day-weekends are just too short for us to reset, do stuff outside of work, have fun and prepare ourselves for the new cycle of madness. With three-day-weekends, we would be in a better than "It is Monday again?" frame of mind on Monday. We would be more motivated and happy.
Helping others feel better is a noble thing. However, sometimes you need to let people feel what they feel for just a moment, before telling them they should feel differently.
