keeping time

i bought mum a new hp and i had it charged overnight. i placed the new phone some distance away from my mum.

as i put mum to bed, she took out her old phone and asked me to help her switch on her phone. i was puzzled why she wanted to switch it on given that the sim card had been removed and inserted into the new phone. she replied she used the phone to see the time when she wakes up at night...

ah-sor! mystery solved! i have always wondered how she knew the time in the middle of the nights cos i did not put any clock in her room...

i obediently switched the phone on for her. once the phone was switched on, i passed it to her and as i looked at the phone, my mind started wondering... the numbers in the handset were so small and i amazed me that she could see the time. it also amazed me that she could interpret the time displayed in digital format. i playfully asked her "so what is the time now?" she couldn't answered and stared at me. i asked again and she gave me a blank look. so i asked her "you said you wanted to on the phone to keep tab about the time right?"...

and she looked at me, took the phone and demonstrated to me how she did it. and as she demonstrated, she said... "i press the keypad so that i can use the light to see the time on my watch..."

hahahaha... my mum is so cute!

me and my mental models!
