When I went to my girlfriend's dormitory, she wasn't there, so I rummaged through her bed and found a carrot! Just then, my girlfriend came back, and I sternly asked her, "What's going on?"
The response from the wronged girlfriend - "It's what was left over from feeding the rabbit yesterday." After saying that, she pulled out a little rabbit from under the bed and then cried her eyes out.
The response from the snack-loving girlfriend - "I bought it as a snack yesterday, is that not allowed?" After saying that, she snatched the carrot and ate it all up in a few crunches, destroying the evidence.
