The volunteer position description emphasizes the type of service I require in exchange for hosting: language teaching/conversation.
Regarding this, we had some exchanges; you performed tasks like washing dishes, cooking, and cleaning the house. I've already changed some things I noticed with you so that it doesn't happen to other future volunteers, like task list and plan since our schedules didn't match, me being a morning person and you being more active people in the afternoon/evening.
