I usually go to bed not too late, but I usually have to get up pretty early.

'Pretty' is very commonly used to mean 'sort of' or 'kind of' or 'a little bit.' Here are two more examples:

  1. I’ve been studying English for many years but it’s still pretty bad.
  2. I thought the food was going to be terrible but it was actually pretty good.



I wake up probably every two or three hours because I grind my teeth and it wakes me up.

'Grinding' means crushing or rubbing two hard surfaces together. See the examples below:

  1. My coffee maker has a built-in grinder. I just put in the whole beans and it grinds them for me.
  2. Most black pepper is already ground up when you buy it.

on average


I think probably I get about six or seven hours of sleep a night on average.

'On average' just means 'about' or 'approximately' when talking about numbers. A real average is a mathematical term that refers to a combination of numbers added together and then divided the number of numbers that were added together. Notice the following examples:

  1. On average, I drink about 3 cups of coffee everyday.
  2. I would say that on average I only drive 40 to 50 miles a week.

being noisy


If my neighbors are being noisy or having a party I usually don't get much sleep at all.

'Being noisy' means being loud. See additional examples below:

  1. I can’t stand being around kids, they are always so noisy.
  2. Please stop being so noisy! You are driving me crazy!



I sleep exactly eight hours a night.

'Exactly' means that the number you gave is not more or less than that number. See additional examples below:

  1. When you take the bus, you need to bring 75 cents exactly because they don’t make change for a dollar.
  2. This sauce is vegetarian but it tastes exactly like meat sauce.
