#16: Unexpected Guests
It's hard to determine which part of this story is more off-putting: the 25-year-old guy bringing his parents on his date or his mother asking the protagonist if she had finished her meal to take home the leftovers. Taking a doggy bag after a date is acceptable when there's a lot of food left, but having your mother do it for you is another matter entirely.
Bringing parents along on a date is certainly unusual, especially for adults. While it may be common for young children to go on their first-ever date, it's not something you'd expect from a grown-up. This situation would likely make anyone reconsider a second date, regardless of how great the person may be otherwise.
