This pattern is alarming and it is NOT normal. For example, if this was just about him being touchy feely, why were you bothered by the way he stares at you? To me, that was the creepiest of all, because he had no business being around you in your nightgown, let alone staring.
Also, if he's touchy feely, he'd be this way around everyone. How did he act with your friend, any sibs, her mom, anyone else? Anyway, that part is easy.
The tough part is what you do next. Ideally, you'd just decide not to spend any more nights at her home. If that gets awkward, then try one overnight but arrange for your parents to pick you up and this would be early the next day.
You can just tell her you "have a lot to do" and keep it vague. Then be careful while you're there and as soon as you're in your nightgown, close that door. See how it goes.
Telling your friend is an option, but try handling this first on your own. It puts her in an incredibly awkward position. Does she keep quiet or does she talk to him or talk to her mom?
Besides, it's never too early to learn how to handle this stuff. When your intuition is telling you something is off, your intuition is correct.
No, you're not being paranoid. I'd keep a safe distance from this man. Don't spend the night at her house again.
(It may be harmless, as I am a 'toucher' by nature and I understand. But you never know who is a pervert or may take it farther.).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
