Diameter Memes

When you ask a mathematician a question, expect the most literal response possible. Instead of explaining that a diameter is twice the length of a radius (which would be helpful), they just replied with "A Radius" - technically answering what the difference is by simply stating one of the terms. The student's confused "Sir?" is the universal cry of everyone who's ever asked a seemingly simple question only to get mathematically trolled. The mathematician didn't even bother with complete sentences - peak efficiency, minimum helpfulness.
