The compliment repeated publicly can become a role someone feels required to maintain.

Praise given once describes something you did. Praise repeated in front of others slowly turns into a description of what you are, and descriptions come with duties attached. The reliable one is not allowed to be late, the strong one is not supposed to need anything, and stepping outside the label starts to feel like letting people down rather than having a bad week.

When you admire something, praise the particular act rather than the permanent quality. And check which label you are quietly maintaining at cost to yourself. You can put it down; it was assumed rather than promised.
