I WhatsApp'd my British doctor to ask for an appointment, and she responded along the lines of
Thank you for your message. I'm really happy to see you but I'm doing voluntary work in [country]. I'll be back in the UK and have some appointments on [date]. Let me know if that works?
I'd like in my response to not completely ignore her mentioning voluntary work and so I want to include a couple of words acknowledging that she said that, and possibly express something positive about it, but without appearing condescending in any way.
What would be the best way to phrase it? I may be thinking a bit too much about it, but I'm looking at the situation as an opportunity to improve my social skills :)
