John: John fell in love with you for being you, he hates change in your appearance and when you cut it short, he didn't speak to you for 3 days.
Paul: When you ask him what he thinks, he asks if you like it first, then agrees with whatever you say.
George: Pretends he doesn't notice until you say something, then calmly states he still loves you, regardless.
Ringo: Doesn't love it, but doesn't hate it either.
