Dear Nana,

I am excited to write this invitation to you to formally invite you to my next birthday party, which will be held on 26/11/2016 at my 5:00 PM at my house.

We will have plenty of pizza, soda, chips and other snack foods, as well as an awesome laser tag tournament. In addition, we will have some incredibly delicious ice cream cake at the end.

All expenses are paid -- just come to the party and have a great time celebrating my birthday with me.

It'll be a lot of fun; I hope you make it!

Dear Alex,
I will celebrate my 23rd birthday next week. Therefore, I want to invite you to attend. If the weather is nice, we'll have a picnic in the garden. We can grill meat, dance for fun. If it rains, we can stay indoors to play cards and eat at the cafe where the birthday party is held. My birthday party starts at 2:00, Saturday, June. We haven't seen each other for a long time. I will be especially glad if you come.
I am looking forward to your reply no later than Friday.
Love,
Riley
