Take pictures of every member of your team drinking water and eating a meal. Everyone should clearly display EXTREME EXCITEMENT with their water/meal.
If you live in a time zone where it would not be appropriate to eat a meal right now, you may instead drink water while pointing to a clock.
Please send this to HQ (by @ing Linus, Misha, and/or Dan on your team's Slack channel) in the format of either (1) a single image file with a collage of everyone on your team, or (2) a Google Drive link to a folder of pictures. Let us know if everyone on your team is comfortable with your photos possibly being shared at wrap-up.
