Hmong parents there are proudest when suitors whisper to their daughters through the wall openings.
Why is that? A family with a daughter that has no such suitor is the saddest family, because that means no one likes their child. Their hope of a prospect son-in-law is slim then.
So, they do welcome such courtship.
Do they pretend to be asleep? Do they pay attention to what they're saying? Etc.? Well, you ask them. I don't have any teenage girl living there, so I can't tell you what I would have done in this situation.
How do you feel when every night, you hear guys whispering to your daughter through the walls? Like, do you just pretend to be asleep while you easedrop? Do you pay attention to what they're saying? Do you have to go patch that hole in the wall everyday only so they can come make another hole to reach through to touch your girl? Hrmm..
