Hi,Ella.
This is Henry.
Since you're not at home today,I'll just leave you a message.
Last week you told me you were looking for a babysitting job.
I have some good news for you.
The couple Mr.and Mrs.Smith living near my house are looking for a babysitter now.
They're both cooks and they have to work at night.
Neither of them can take care of their one﹣year﹣old baby girl.
She's really lovely.
I'm sure you'll love the little girl.
If you do the work,you only need to take care of her and play with her from 6:30 pm to 9:30 pm.
Since you've looked after babies before,I'm sure you can do the job well.
The couple say they can pay 20 dollars an hour.
If you're interested in it,please call me back.
I'll introduce you to them.
Believe me,they are very easy to get along with.
I'm sure you'll like the family.
That's all.
Bye.
