"You know when you eat something for a long time and you eat sooo much that you finally get bored of it and have to be separated for a while before you try it again and say 'oh my god I've missed this so much'? Well, you're the food I've had too much. Almost 18 years is too much. So when you move away in ten years or so into your own place that'll be the time I get used to not having you. Then five years later, you'll come over and I'll say 'oh my god I've missed you so much.' So just wait about 15 years, then you'll be the food I like again."

Btw she said it in a sarcastic tone so please don't bash my mom. She's a good person and I hate seeing that.
