Combeferre is such a sarcastic little shit though, seriously.
You can just imagine his glasses falling off one day and Courfeyrac is just like “Omfg can you see anything?!” so Ferre just drops to the floor and fumbles around, purposely missing them as he goes “Jinkies! Where are my glasses???”
And Grantaire is just pissing himself with laughter in the background and he and Ferre just bond over their sardonic asshole-ish tendencies.
