Yes, but how did you know that there was a cobra, Mrs. Wynnes?
You were right colonel, a man didn't panic!
It crawled across my foot.
The theme is that your gender doesn't impact your courageousness. This is because both Mrs. Wynnes and the American man don't panic at the sight of the snake, showing that just because you are a man you aren't braver than a woman and vice versa.
An example of dramatic irony is when the American, hostess, and audience know about the cobra, but the other guests do not. It is considered dramatic irony since it contrasts between what most of the characters know and what two characters and the audience realize.
Situational irony is demonstrated because the audience and other characters expect the colonel to be right because the American man was the one who stayed calm. However, the opposite is the reality as it is found out that Mrs. Wynnes was the courageous one when she says that the cobra slithered over her foot.
