Okay, let's fill the email with correct tense:
Hi Beth,
Last night I (a) **had** to wash the dishes because our dishwasher broke down!
I (b) **hate** washing dishes! Usually Mum (c) **does** it, but she (d) **was** out. She (e) **went** to the theatre with a friend. The dishwasher is fine now, so I (f) **don't have** to do them today. I (g) **am sitting** in the living room at the moment because I (h) **want** to watch a film on TV. I (i) **saw** it last year and I (j) **like** it so I think I'll watch it again!
Speak soon,
Gemma
