1. You like their apartment
2. They have the same name as the lead singer in your favorite band
3. They live off the same subway line
4. They are from the same region of the country as you
5. They have a Boston accent, an accent which seems cute and endearing at first but becomes increasingly irritating the more time you spend around it
6. They live approximately one block from your favorite bar and two blocks from your favorite burrito place
