Mr.CarloCat's Things

Okay, so I saved a photo of a manga from someone’s answer to a question, but I don’t know which manga it’s from. I don’t remember the question it was from, so I can’t even ask that person :(
Since I don’t know how to upload an image on here, here is a description of the photo:
[in a single panel]: A young man with light colored hair and wearing a gray t-shirt is lying on his side on the floor with a tired look on his face. He’s wiping the floor with a cloth and saying, “What the hell am I doing? Am I garbage? No, that’s being rude to garbage.”
Does anyone know what manga this is from?

P.S. I would appreciate it if someone could tell me how to upload an image (it would help answer my question, too!)
