I bought a new phone because
I failed the English exam because
I couldn't go swimming because
I argued with my girlfriend because
I couldn't find the restaurant because
I didn't wake up on-time because
I couldn't eat the steak because
I couldn't catch the flight because
I couldn't read the e-mail because
I didn't recognize my friend because
she had come home late.
I had drunk too much coffee
I had left my passport at home.
I hadn't studied enough.
I had lost the directions.
my friend had recommended it
the chef hadn't cooked it enough
she had put on a lot of weight.
I hadn't brought my glasses.
I had left my swimsuit at home.
