Me! Papa Dom

Last Monday i realise that my daughters are now not a small kid i use to know. They are now teenage, and with all new things in the world of teenage, i think i'm loosing my daughters. I don't recognise them anymore. A years ago i always thought that my daughters will never lie to me about anything, at least that was what i expect them to do. No lying. No secrets. But yesterday i found out that they have a different mind when they come to teenages. They start telling lies, and keep lots of secrets. I feel that they didn't need me anymore Thats a bad feeling and a sad one. Am i too emotional? Am i over protected father?
