roadie

Theoは行方不明だった友達のAprilを見つけました。
“My father thought it was so cool playing at Miller’s.”
“How’d you get in the bar when you’re thirteen years old?” Theo asked. “I don’t know. I was with the band. It’s not like I was drinking and smoking. The next day we drove to another town, maybe it was Roanoke, where the band played to an empty house in an old music hall. What day was that?” “Thursday,” Ike said. “Then we drove to Raleigh.” “Were you in the van with the band?” Ike asked. “No. My father had his car, as did two other guys. We always followed the van. Zack was the driver and the roadie. My father kept me away from the other band members. These guys fight and bicker worse than a bunch of little kids.”
