SOMETHING OF A HABIT

Yesterday evening I went over to Lai Yoong's house to show her how to create a photo album for her Facebook.  She and her hubby were having trouble posting the photographs and asked me for tips on what to do. 
I told them that it was actually very easy but then they said that it was something that I do everyday and has become habitual and easy for me.  If someone were to ask me to change the rubber of the tap or to change a plug, I would be at a loss.  I don't do such things on a daily basis and so it would be something difficult for me. 
Anyway, Lai Yoong managed to learn how to create the photo album for her Facebook account and so it was a successful lesson for this teacher.
