Hi Tom!
How are you? I’m great.
Are you available on Sunday?
My mum has a few plans for the upcoming weekend for us.
On Sunday, we planned to go to the beach. This trip will be amazing! I think it will be very fun. We have planned a lot of activities we can do there such as surfing. On Saturday, I need to do homework. There’s a lot of homework I need to do. It will be boring. Please reply to me soon. Hope you can go with us.
Thank you.
Love
Pat
