I think of people getting their neck stretched and getting covered in feathers, like becoming an ostrich
That's weird to think of. Why would you think of people like that?
Because I think it's funny to see them doing that, ostrich are crazy animals.
Sometimes our imagination gets weird and funny, but I would be careful with thinking like people are becoming ostrich because you may try to turn other people like that even if they don't like it. Worse, you may actually harm them or injure them in the process and you may not like the result and you might end up doing something illegal.
It's just a fantasy, besides it's a little too big of a commitment for me.
That's good then that it will only stay as a fantasy and not harming others in real life. Separating reality from fiction is a really important thing to realize! You might think of more cool things if you keep it up.
