I had a happy thought, and I am indeed announcing this despite if anyone cares.
So if you've watched Guardians of the Galaxy (at least the first one), you would know that Peter Quill was raised by the Ravagers (space pirates) , after being captured/kidnapped/"picked-up" by their captain, Yondu. Yondu has a habit/obsession of collecting little figurines and putting them in his control panel.
Without trying to give away spoilers, Quill tricks Yondu into giving him a little orange haired elf thing, and Yondu smiles/laughs, and I have two theories as to why.
The simple way: he was proud of teaching Quill how to lie and trick effectively, and he let it go.
The long way that made me smile for a few minutes:
What if when Quill was younger, he would find these little figurines and try to give them to Yondu (he had no parents, he was the closest thing he had, and was probably the one that treated him the most decent), and at first Yondu was like "what the heck no" and that made Quill sad, (maybe he first tried giving him the elf and kept it for himself). But young Peter Quill thought that maybe he just didn't like the elf so he tried to find other small things that maybe Yondu would like, and when he did find something Yondu just took it to stop the kid from being sad/crying, so over time Quill started finding more and more of these thinking Yondu liked them, and with Yondu putting them on his control desk or panel or whatever it's called, he had no reason to not think he didn't like them. So after years and years a grown Quill had swapped the [REDACTED] with the elf, and Yondu was smiling remembering the time Quill first offered it to him.
If you are curious, yes, I am obsessed with those movies, specifically 1 & 2, and Baby Groot is my favorite.
