Embarrassing

I noticed lately that when I bend down to kiss Alice during school drop-off, she lowers her head into the collar of her coat. Suspicious. So I asked her about it at bedtime and she confirmed my worst fears - "Mummy, it's embarrassing when you kiss me on the mouth" Argh! We came to a healthy compromise, that I could kiss her cheek and give her a hug. But there was more - she wants to make sure I don't wave and say goodbye for too long as she walks away into the playground.

Shall I simply hide in the shadows or behind a tree to spy on her? Can I read her diary? Break into her Facobook account? Don't parents have rights?!?!?!?
