A man wearing dark knee boots, a green cape, and a hat with two big feathers on the front is sitting by himself on a bench in front of a building with a blue and white patterned piece of wheeled luggage to his right while he rests both his hands on a walking stick.
A man sits by himself at Mardi Gras.
Answer; Just because the man is at Mardi Gras it doesn't mean he is celebrating.
The man may not be at Mardi Gras.
Sitting on a bench with luggage in front of a building wearing a hat with two big feathers on it doesn't imply that the man is at Mardi Gras.
