My girlfriend and I were 17 when her parents left for a couple of weeks and we decided to live together. It is clear that young blood, nights (and sometimes not only nights) passed violently. During this time we lost a lot of weight, and when I got home, my mother, gently speaking, was in shock. When asked what happened to me, I replied that we were just running in the morning, and my father added, “We were jumping at night.”
