Final answer:
Caedmon, from Bede's 'History', avoided singing at feasts and would leave before it was his turn.
Step-by-step explanation:
According to Bede's History, Caedmon did not like to participate in singing at the feasts. He was known to have left the feast before it was his turn to sing. Caedmon's avoidance of performing reflects a theme of avoiding public participation, similar to characters in other historical and literary texts who experienced discomfort with particular social situations related to feasting and the sharing of talents or entertainment.
