presentation

Yesterday afternoon, as usual I made a small talk with Fay after school. The topic was about his school activity. He began his chronology .

Fay : At school, we made a presentation, mom.
Me  : Really? in a group?
Fay : yes, I am a leader in my group. I made some drawings for presentation on a cardboard. My other friends decorated it because I am good at drawing among them (with his pride expression).
Me : What's the title of your presentation?
Fay : Energy Conservation, in this case electricity.Most of groups preferred water conservation. And I represented my group to explain about the presentation.  I didn't use some notes to present but in other groups, the presenters still read their notes. The funny thing, my friends from another group were afraid to present.So, my teacher said that they wouldn't get score if they didn't present. Finally, they made it
Me : It sounds great.Tell me how you presented it. What did you say in front of class about your presentation? . I am curious. (with showing my curious face).
Fay : Well, firstly all my friends in my group opened the presentation. We said " Assalamualaikum wr wb,we are from group 4 will present electricity conservation". After that I explained with my ownself like this "Ok friends, electricity conservation is important because the material to produce electricity is limited, such as coal and oil. But now we can produce electricity with using windmills".  I also gave an example " If you are at home, you turn on Air Conditioner, switch on TV but you open your window and you don't watch tv ,you play your toys. So, you have wasted the electricity energy. You don't make the conservation. Are there my friends in this class waste energy just like the model?"
Me : what was their response?
Fay : They didn't raise their hands. I think they save electricity energy.
Me : They suppose to do so and you do, too.
Fay : yeaaah.
Me : Hmmm...but there is one thing I want to know from you.
Fay : What else? (with sluggish face)
Me : What were the materials for making presentation paper? You didn't bring anything, did you?
Fay : yaaa, I know. I forgot to bring  and so, did my friends. But, we bought all of materials at the store nearby.We bought a cardboard, glue, stickers, glitters, markers.
Me : How did you pay them? You didn't bring some money this morning because I brought you some food.
Fay : We collected the money. Some paid rp.5000 and rp.10000.
Me : and you ?
Fay : I gave Rp.2000. You must ask how I got the money, right? I was lucky, mom. I found it in the school yard and nobody lost it. and my friends didn't complain for my small contribution because I saved them to make our presentation running well.
Me : @^%*& (speechless)
