10 minutes countdown

Just now, Gordon asked me to do a 10 minutes countdown for him. So, i went, "10, 9, 8, 7....". He stopped me and repeated, "Mama, 10 minutes countdown...". And so, i went, "10 minutes, 9 minutes, 8 minutes...", and got stopped again. "Mama, 600 seconds countdown...". Me thinks, *haiworr... It's 60 seconds/minute x 10 minutes! Wtf....*. Sott gar.... ask me to do a 600 countdown! Go to sleep, or go sleep with the dog!
