Having one aunt or uncle who gets you when your parents don’t is a quiet kind of luck. Tell them.

An adult who is not responsible for you can hear things your parents cannot. They are not paying for anything, not accountable for how you turn out, and not frightened in the way a parent is, which leaves room to just listen. That makes one well-placed aunt or uncle unusually valuable at your age. Plenty of people never get one.

Tell them what they are to you, in words, because they almost certainly do not know. Then keep the relationship going yourself rather than leaving it to family occasions.
