As a host I am very committed to making my guest's stay as memorable as possible. I actively try to figure out what my guests are looking for out of a stay at my home, either privacy or getting to know new people.
If they are looking for a privacy I go out of my way to only be around if they need something, but I put in extra effort to make sure they have everything they could possibly need and maintain their privacy.
However, if they want the experience of getting to know new people I extend genuine invitations to activities that I am doing that may interest my guest. I have a very active life, especially during the summer time. Just about every weekend is busy with racquetball tournaments, social events and etc.
