Hahaha awww I know exactly what you mean. I had a remarkably similar conversation with my mom after I got into Sinai (she lives right by NYC). Basically, it went like this:
"Mom, I got into Sinai!"
"Oh wonderful! I'm so happy for you. That means you're going to drop Vanderbilt, right?"
"Well, I don't know yet, I'm going to have to look at both of them."
"But Sinai is your first choice!"
"Uhmmm...I never said that..."
"Well, you should have! I liked it for you!"
"Yeah but I'm the one who has to choose my school Ma, your first choice is sort of irrelevant"
"But it's near home!"
"Yes, yes it is"
"So, you'd rather be in the SOUTH than here?"
"Mom, the South isn't like, Hell. It's just the South."
"....why must you go so far away from me?"
sigh.
