Description Sticker Technically the glass is always full
What would amateur psychologists do without glasses that are 50 percent filled with water? Because only then can they categorize people as optimists and pessimists: the former see the glass as half full, while the latter would call it half empty.
The "Technically, the glass is always full" sticker shows, however, a third approach: The glass is always full! It is half filled with water and half filled with air! Even the aforementioned amateur psychologists are left speechless. ;)
