Going once… Going twice…
Just double checking, is it supposed to start at 9am?
Hi. I’ll start sharp-ish at 9:30, so I put 9 for 9:30 to give people time to settle in, make coffee etc.
Hi Brendon, my apologies for such a late notice, but I won’t be able to make it this early tomorrow. I’m so sorry for not letting you know earlier, something just came up for me 
Thanks for letting me know. Hopefully you can make another one!
