Final answer:
A host is someone who invites guests and provides them with amenities, while being hospitable refers to the quality of warmly welcoming guests. Both roles are related to the joy of entertaining guests and the social dynamics involved.
Step-by-step explanation:
The terms host and hospitable both relate to the activity of entertaining guests. A host is someone who invites and receives guests, typically providing food, drink, and company, while someone who is hospitable is characterized by their warm, welcoming, and generous reception of guests. The presence of a host who is jovial and generous, like Old Baltus Van Tassel, can contribute significantly to the enjoyment of the gathering, as can the shared realities and expectations between host and guest. However, there can also be stress involved, related to fulfilling social expectations or adhering to the rules set by the host to ensure a pleasant experience for everyone.
