The struggle is real（＞ｙ＜）Poor cellist, his companions are enjoying while he gets to stay alone and play the same eight notes over and over. (One of the cellists in our section plays the same rhythm the cellist in the video did when he started plucking XD He does it when he becomes frustrated with the part!)
Thank you, glad you enjoyed it (＾ω＾) And, poor piccolo player.
