Neighbour letting children play in the driveway near naked?

[yonnie2011]

We have a neighbour who lets her 3 children play in the driveway with just a pair of knickers on. Her youngest son and daughter are about 3 years old max so it is expected at that age but her other daughter is probably at least 9/10 years old (she is much bigger and taller than my 8 year old DD who is considered tall). Is it just me or is that way too old to be in outside with no top and just a pair of knickers?
I would understand if it was just their garden but they play on scooters etc in the driveway (we live in a cul-de-sac) all the time. Today I went out with DS18 and DD8 and as we walked past them we tried not to look and my son was obviously very embarassed.
I would ask the parents to encourage the older girl to cover up a bit more but they moved in just before the outbreak from abroad so they don't speak English (I think they are east European). Should I put a note in their letterbox so they could translate it maybe?
Sorry for the long post but I just want to make sure I am not being unreasonable before putting something through the letterbox.

Why would you be embarrassed by something you're not looking at?

The old guy across the road walks about for around 6 months of the year without a top on (clearly has better cold tolerance then me) nobody in the street is embarrassed or cares, just as I'm sure he or the other neighbours aren't when the dc start to lose layers when it's hot or having water fights. I'm sure if they did mind they'd just avert their eyes!

@midnightstar66 - lol! I know the type you mean. But also don’t u think it’s different as this is a young child and it’s definitely a safeguarding issue. In your own back yard this would be okay but not in front driveway where everyone can see her. She’s too young to understand how sick some people are and how they might be viewing her and having disgusting thoughts. I would be really upset if this was my niece or something as she’s the same age.

Incase my comment gets misconstrued- I meant the old man walking around in all weather practically naked. I have one in my street!

There is also a difference if anybody walks around in shorts only, or in pants only...

I'd be more concerned about my son in this scenario tbh. Creepy!

What nonsense.

So an 18 year old man being "embarrassed" by the sight of a child's body is not weird? Ok

I would be more worried about why an 18 would be embarrassed by this. I find that very odd.

Lol i think your post should read "should I be worried my 18yr old son was made visibly awkward by a 9yr old in pants"
