[waitwhat?]

Not particularly a gift per say, but our team will have a "Senior Sign Off" every year at the last event of our season. Usually we have atleast one away event that requires our team to stay in a hotel. The last night that the team is together, sometimes at the hotel, sometimes at a restaurant, our lead mentor will have all the graduating seniors line up and speak one by one about what being part of team 869 and FIRST as a whole has done for them, what they've learned, the relationships they've forged etc.

It's just a feel good moment for everyone, the seniors get to voice their appreciation and share some of the favorite memories, the younger students get a chance to reflect as well, and we as mentors are motivated even more by the impact we might've made.

Word of caution though, sometimes it can get kind of emotional, some students just love robotics so much!
