Magnanimous - generous in forgiving an insult or injury; free from petty resentfulness or vindictiveness:
Luckily you don't have to use the word magnanimous in a sentence, only in a photo!
Despite his sad dog eyes, Simon is a super forgiving pup. When he brings his toy to play and I tell him he has to wait because I am busy, he does so patiently and is always happy happy once we make it to the backyard and he gets to play frisbee. He is indeed a magnanimous boy!
What does magnanimous look like to you?
