Thank the person who drove you to every practice. Those miles were a love letter with a gas receipt.

Devotion often takes a form nobody would recognize as devotion at the time. Early mornings, waiting in a parking lot, rearranging a whole week around something that mattered to you and not to them: that is what care looks like when it is expressed in logistics rather than words. The person doing it rarely describes it as anything at all.

Tell them you know what it cost, specifically, mentioning one detail you remember. It will probably be awkward and they will probably deflect, and it will still land. Say it while it can be said in person, which is the version that really works.
