It was a beautiful sunny day. After finishing my daily routine on the treadmill, I noticed how empty the gym was, with only the front desk attendant around. So, I took advantage of the situation and snuck into the yoga room to practice singing some high notes. Who would bother, right? The walls are soundproof, so it was the perfect spot. When I got home, Mom scolded me. She had received complaints from the gym manager about my singing. I guess that later on, there must have been other members who wanted to use the yoga room, but couldn't because I was occupying it. I feel so sorry and regretful. Maybe I should apologize to the gym manager tomorrow.
