You are happily alone in a bar, but someone will not leave you alone. Your polite rejections do not work. The pestering goes on until you leave or someone intervenes.
It is not an unusual scene - many women will tell you this has happened to them.
这不是一个不寻常的场景 - 很多女性会告诉你这在她们身上发生过。
So when British journalist Amna Saleem tweeted about a stranger posing as her friend to help her escape unwanted male attention in a London bar on Saturday, it sparked an international conversation, much of which focussed on how other men can step in.
More than 430,000 people liked the tweet and almost a thousand people commented with their experiences.
In reply to Saleem’s tweet, @TheOmegaGeek shared a story of pretending to know a woman whose boyfriend was "screaming at her," and giving her money for a taxi home.
Another user, Jamiel Pridgen in New York, US wrote, "Some dude was bothering this lady once on the train and she was alone so my brother pretended to be her husband and the guy left. 10 years later he is her husband".
But some women shared experiences of being followed after rejecting male attention, or being hassled on public transport, or of having to seek protection from other couples.
Nathan Moore, in the US, lays the blame at society teaching men to be "persistent".
@KittenRescuer replied: "A lot of our pop culture rewards this. For once I’d like to see a show depict a romantic relationship in a non-creepy-way".
However, not everyone welcomed the idea of a stranger trying to help them with close personal contact.
"That’s really nice, but if a random woman hugged me at the same time as a pushy bloke was hitting on me I think I’d go into ’weird overkill’ mode," wrote soyaburger.
