Let’s be clear about something that society likes to dance around:
When a teenager develops a crush on you, it is not a compliment to your status, your looks, or your "game." It is a test of your integrity, one that far too many adults are failing.
That child is not looking for a partner; they are looking for validation, often mimicking what they see on screens, completely unaware of the power dynamics they are walking into. They are naive, but you are not.
Your job as the adult in the room isn’t to "play along" because it strokes your ego or use the loophole of "well, they made the first move." Your moral obligation is to be the hard boundary that they don’t have the wisdom to set for themselves yet.
Treat them like a younger sibling. Ignore the advances. Shut it down. Because 10 years from now, when the confusion of puberty fades, that person will look back at you.
Do you want them to remember a safe adult who protected them from their own foolishness? Or do you want to be the villain in their therapy session who took advantage of a child who didn’t know any better?
