How we cite our quotes: All quotations are from You Can't Take it With You.
Quote #4
TONY: I want them to meet you as you are, not some trumped up evening with everybody acting unnaturally.
Tony is more than a little in love with Alice's family, presumably because they're so much more fun to be around than the grumpy Mr. Kirby. He seems to have hoped that they would win over his own family—though it didn't really work out.
Quote #5
MR. KIRBY: Mr. Vanderhof, you once told me I was a failure as a father.
GRANDPA VANDERHOF: Oh, I didn't mean that.
MR. KIRBY: I know, but I am.
It's ultimately family that transforms Mr. Kirby— both Grandpa's family, and his concern about his own son Tony. Family, at least in I Can't Take It With You, makes you a better person.
