Do What Mumma Says

This actually happened this evening:

Little Miss Haana was telling me this evening how at school her toenail broke and hurt. But she was able to peel it out, and that it doesn't hurt anymore.

I told her I need to cut her other toenails.
To this she said grown-ups actually grow their nails. I said I don't. But she said Miss Simone does grow her nails. So, grown-ups grow their nails.

I thought about it for a second and then said- some grown-ups do somethings, some another. But she needs to do things that work for her, and what she likes instead of what works for other people; or what other people think she ought to do. I gave her an example how some people may say what girls can or cannot do. But she needs to do what she feels is right by her.

After a pause and added- "Do what feels right to you, and also what mumma tells you to do", ( i had to add that part).
But, I guess it was already too late when she replied: "But I have to do what is right for me. Not what anyone else says".
