come late

huft...today i couldn't follow my Structure Class,because i was late 30 minutes.Actually,this morning i woke up early,at 05:00 am,but there was a problem that made me come late.I couldn't find my wallet,i thought it was lost.So,me and my friend searched it everywhere,fortunately we could find it in my cupboard.But,the other problem came,when i looked to my watch,i was very shocked,it's 07:15 am,and then i ran quickly,i was so tiring at the time,because i had to go to up floor.Unfortunately,when i arrived in my class,my lecture just said "YOU MAY COME NEXT WEEK".
