write a short paragraph about an activity which can spoil family

I would like to tell you about my family.

I love them, but sometimes we have quarrels between us.

And it can be caused from TW, computer, because everyone in our family wants use it.

And in my opinion, the worst problem - is a lie.

For example - you got a bad mark and don't want to tell about it to your parents.

Or you stole sweets from your brother...

I hope that you will be respectful to your  family.
