Listen to the dialogue. Why didn't Mark call Jane?
Jane Look at the time. You said you'd be here by 4
o'clock. Where have you been?
Mark Sorry I'm late. I know I've upset you. I didn't
mean to.
Jane So, what happened?
Mark You see, my skateboard broke so I had to
walk instead. And I'm afraid I lost my helmet.
Jane You mean the one I bought for your birthday
last month?
Mark Yes. I don't know how it happened.
I thought I'd left it at school sol
went back looking for it, but it wasn't there.
Jane Well, you know I don't like it when you're
late. Why didn't you call me?
Mark I couldn't call you because I hadn't charged
my phohe. I'm really sorry.
Jane Well, please don't be late next time.
Mark Don't worry. It won't happen again.
I promise.
