Just now i had my maths tution.It was supposed to start at 5,but he came at 5.20pm.While waitng for him,i felt very bored,so i fell asleep on the sofa.When the teacher came,he waited at the for a few minutes and i haven't wake up.Then i heard the bell ringing-i woke up.When he was teaching ,i was very tired.I couldn't concentrate.When shown me some questions i was horrified,pie was =3.141592654 without using calculator[believe it or not is up to you],this perks me up.I wanted him to show me some more,but he say must finish homework first.I agreed.He shown more ,i dare not look some more.I was shocked .I got out immediately after it.
