TFW you open a bag of trail mix only to discover you got one that has peanuts in it. And you don't like peanuts.
@Kurtroedeger We once got an instant breakfast labeled, "macadamia nut." Husband found only one in the whole package. And then pointed out: "Well, they DID say 'nut' and not 'nuts.'"
@estherschindler o r if you do like peanuts, get the 'peanut lovers' check mix and only find one peanut in the whole bag.
