I agree, context is indeed everything here.
The context is a lone 14 year old girl having an unwanted interaction with an adult male. About underwear.
14 year olds do not consider themselves “in control” in any interaction with adults.
Children and teenagers are taught to respect adults and do what they tell them. Especially teenage girls.
Even when they are uncomfortable and alarm bells are ringing it’s hard for a young teenager to get themselves out of that situation.
I know, I was that teenager more than once. If you haven’t ever experienced that, I’m really glad but suggest that you are very lucky.
The man doesn’t need to have asked actively creepy questions for the interaction to be uncomfortable and disturbing.
He doesn’t need to have been intending to hurt her for the interaction to have been harmful.
So context is indeed all.
Because the reason men don’t approach teenagers in lingerie departments is because there is absolutely no bloody context in which a teenage girl would be ok with that.
