Many people missed classes today.
Some are homesick.
Some spend a lot of time playing computer games - but fail to do their homework.
Some feel down because they don't try and improve their English and as a result are way behind with their studies.
Some feel their bedroom is too small.
Some do very little work in class.
Some rely on others to tell them whether there is Sociology homework.
Some persist in speaking Chinese/Russian when they know they should be using every minute to improve their English.
Not everyone is happy with their food, their teacher, their textbook, their money...their life.
This is for you
