Hurry Up! Illustration
On the day of club competition practice, Sunshine overslept๐ Fortunately, we decided to gather on a tennis court not too far from home, so we decided to run on the board ๐ฅ I was running hard across the alley, and I got a call from one of the members of the same club ๐ "I'm going to start practicing soon. When are you arriving, Sunshine?" "[m = (n^2+1)/2 = (n^2 + 2n + 1)/4 + (n^2 - 2n + 1)/4] = Arrives in N minutes "What are you saying ๐ค?" Don't think about the time. Run, Sunshine Watch out for stray cats, too! ๐๐ผ
