Dear John,

I hope you are receiving this mail in good health. I know we haven't met for ages, but I'm thrilled to let you know that my college has arranged a 'CNN tower' tour for the department of Civil Engineering for a research project, so I'll be visiting your city Toronto from 23rd March to 29th March 2020.

Firstly, I can't believe it has already been three years that you moved to Toronto. As you are an explorer, I hope you have travelled over your city and can guide me about the touristy places. I have heard a lot about the 'heritage train station', the exquisite downtown and riverwalk area.

Secondly, as we'll be working on our project during the week, I was wondering if you are available during the weekend. If so, we could plan a party.

As three of my classmates are accompanying me on this project, it would be a good time to hang out together. They love retro music just like you, therefore I think they'll enjoy your company.

Let me know what you think about this plan, I hope to see you then.

Cheers,
Alex
