Iam a college student invited to spend several days at a new friend's home which includes a $3K football ticket to a very sought-after game provided by the dad! I come from very modest circumstances. Do I bring a hostess gift-if so, what would be appropriate? Shd I send a thank you note to Mrs only or Mr & Mrs due to the football ticket? Shd I also send a gift after the visit? What is the appropriate etiquette for this occasion?
