We have been super obeservant, with a side order of allowing the teens 19 their head (within reason)

We announced tonight that this house is going back to lock down rules in the middle of October, if not well, it was remarkably well received.

What. Why.

A bit more context would be welcome here I think

We have allowed the teens attached to my DC to come and go for the summer, found out last night that DS was allowed to stay at his friends house, but only if he slept in a tent.

So........ my DS is worthy of their garden, and yet they think that we are so lovely for having the boys including their son, sleep on our couches

Game over, I was,am shielding, happy to resume to see this winter through.

I guess each household handles things differently, a bit like taking your shoes off, or not, when visiting.
Do whatever you think is right for you and your family but expect others to do the same. I wouldn't take it personally.

Nothing grudge induced about it, I was heading that way anyway, and the realisation this week that this particular set of parents are more than happy to allow their son to stay in our house at least once a week, and yet my son is made to sleep outdoors.

Tighter house visitor rules were coming anyway, they have just been fast tracked.

A deferred grudge-induced lockdown. Huh. Well. Right.
If by the middle of October their mammies are letting yours in, are you going to continue the lockdown rules to equalize the time disparity for your entire six month summer laxity?

Eh?
Why don't you just address the core problem itself?

I'm not sure what's going on here, but being passive aggressive is never the way forward. Just communicate openly and honestly.

OP, if you're this passive-aggressive with anonymous strangers on a forum, what are you like with the parents of your teen's friends in RL? Just be straight with them.

Frankly, more fool you for allowing teenagers not of your household to kip on sofas etc inside your house, if you've been shielding! Why would you DO that? My younger son had a sleepover with a friend and we put them both outside in a big (5 m) tent which I think worked well. I don't imagine his parents felt slighted in any way.
