16. Drinking too much
Getting intoxicated at your own house on the holidays is gauche, but drinking too much at someone else’s home on a holiday is embarrassing.
17. Overindulging on food
The urban legend about eating too much turkey is that it contains the amino acid L-tryptophan that increases sleep-causing serotonin and melatonin. However, turkey has about the same amount of tryptophan as other meats. What causes you to crash is eating the truckload of carbs during the meal. Most hosts are pretty understanding about guests catching some Zs after dinner, but don’t take advantage of their hospitality.
18. Dining and dashing
People drive from place to place over the holidays, visiting family and friends. Your hosts will understand if you plan to go elsewhere for dessert, but guests should let them know ahead of time, and not bolt from the table once dinner is done.
19. Overstaying welcome
Cleaning up, putting chairs and tables away, and storing leftovers is a big job. Unless the hosts have taken you up on your offer to help tidy up, don’t stay too late.
20. Taking leftovers without asking
Between the slices of turkey meat, mounds of potatoes, trays of green beans, and platters of sugary treats, the Thanksgiving meal produces lots of leftovers. That doesn’t mean you have free rein to take whatever you desire without asking. Doing so is a near-certain guarantee you won’t be invited back.
