I have talked to Dr. Kevin and he kindly offers another slot for you guys this Friday afternoon (1-4pm). If you would like to have a practice with him, please let me know ASAP that you are available and care to attend so I can let him know that it is happening.
You should thank Dr. Kevin very greatly since I have already made it clear that it is no way his fault and there is no need to re-organise but he still does it for you.
