modal verbs:necessity,obligation and prohibition

Dear Dave,

Don't worry.You don't have to pay for everything.Most girls are happy to pay for their half!.Here are a few more or my dating tips:

.you must arrive on time.You won't make a good first impression if you're late!

.you needn't wear designer labels for your date,but you have to make an effort!.Dress in smart clothes,not scruffy ones!

.you mustn't talk about yourself too much.Ask lots of questions!

.you need to pay your date lots of compliments.Remember,she's probably feeling nervous too!

Good luck,

Dora
