You'd like to celebrate your birthday party in McD. You tell your mom & she says it's not possible there because that's unhealthy food. She says your doctor prohibited you to eat junk food. Instead she allows you to have the party in garden

You go to a clothes shop & the shop assistant offers you help. You say you're looking for a present. Ask her to suggest you what to buy. Say the present is for your dad. Tell her you don't have enough money to buy something very expensive.

You want to go to a party and you ask permission to your dad. He tells you that you can't go and reminds you the obligation to do your homework and study for an important exam you have tomorrow.

You want your parents to buy you a motorbike. So you request your mom politely if they can buy it. She answers you that it's not possible now. She also tells you that you don't need a motorbike. She obligues you to walk to school.
