Dear Claire,

it's been a long time since our last meet. How are you doing? I know that you have just come back this country, have you got a place to live? If you don't mind, you could stay at my home. Ah, and this is the most important thing. This Saturday is my parents' anniversary day. They often have a bbq party with neighbors, however, this is the 30th anniversary, so my parents want to have a big party with anyone that could come. It's gonna be amazing and fascinating! Will you join us? The party will start at 6 AM and end at 11 PM, cool, right? Let me know in the next reply, my friend.

Best wishes,

(your name)
