Bonjour :)
1 Calvin wrote a letter to himself because no one ever writes to him.
2 That cat hurt itself by jumping from the window.
3 That was a good essay. Did you write it yourself.
4 My cousin keeps looking at himself in the mirror. You know what teenage boys are like!
5 We buy things in the DIY shop and we do everything ourselves in the house.
6 Two men killed themselves in a helicopter accident last week.
Voila j'éspere t'avoir aidée :)
