That is so nice!! I also got a few IMs/txts from quite a few of my former exchange student guests in February (when # of confirmed cases began spiking in Korea) asking if Henry and I are okay. We've been messaging back on forth once every couple weeks since then to sort of "check up" on each other and hear what it's really like for everyday citizens beyond what we see on the news.
I have just received a four-day August booking (the only one in my otherwise empty calendar) from a German couple who we've hosted before. Their reason, when I asked; "To have and to share some hope of normality".
