Dear Bayo,
Thank you for your invite, that is extremely kind of you and i really appreciate your generous offer to join you in Paris for summer. I'd really like to visit unfortunately I won't be able to make it due to the fact of my tight schedule.
I was recently promoted to head of my department and this currently demands that i spend more time at the office. I am sure you would remember how much i love to take responsibility when we were back in college, and we worked together as joint head of class, Good memories!
I would love to join you as soon as my leave application is granted, please let me know if you would be open to we're postponing for winter due to the fact that is most likely the time my leave would be granted. I am aware there are consequently a number of outdoor activities we can do together and I can't wait for us to have fun together. If anything changes at work and I am able to come sooner, I would let you know.
Looking forward to hearing from you!
Ridwan
