When the phone vibrates in class...

Phone vibrated during SS tutorial today. Grandmother's house number, Olivia, time, school, the maid, diabetic uncle... pause... reject. Vibrated again. Grandmother's house number, the maid, diabetic uncle... pause... If it's important, is it that bad till I'm the last possible option on their list? Got out of tutorial class, pressed accept, pressed phone to ear...

"Hello, jie jie ah, ask you how to spell 'alien' ah?"
"Huh? Olivia, you call me just to ask me how to spell alien ah? I'm in school now leh! Ok ok, A-L-I-E-N."
"A-L-I.."
"A-L-I-E-N."
"A-L-I... not 'a' ah?"
"No."
"Ok."
"A-L-I-E-N ah. Ok, don't call already, I'm in school, got class."
"ok, bye bye."
"bye bye."
