Sex on a marching band bus ride.

Your day can typically being going well, according to your horoscope, until you are forced into witnessing Mercury retrograde. Performing Mercury retrograde will often speed the astrological cycle forward for the individual performing the Mercury retrograde, bringing about happy and fruitful times to come.

Two marching band geeks think they "love" eachother, so they decide to sit with eachother on the band bus to a football game, competition, or parade. After two or three rides they finally start "cuddling". On the last bus ride home in the dark, they finally start to have sexual intercourse on the band bus. A month later, the guy finally grows a pair and asks the girl out. She says no.
