Ah, reckon this was just bound to happen sooner or later. Neighbours complaining bout this baby and me having too much fun, that is. Not to mention too long and way too often, too!
Surprisingly enough not the neighbours I had suspected most, but the single mom from the apt. below ours. Nonetheless strictly by the book. I.e. first banging at the wall from below in the still of night, probly waking up everybody a few floors in both directions. Then the next day ringing while my mate still sleeping, complaining 'I didn't get a wink of sleep for two days now.'
Actually the night before Baby and me had been practicing the explicitly romantic variety, contrary to like three nights ago, probly having been he loudest while staying in my apt., but nevermind. And just for the record, even then, though we weren't gagged nor stifling ourselves, weren't actually loud either.
Definitely quieter than them regularly banging up the roller blinds plus stampeding through the apt. and slamming doors when they're late and in a hurry getting off in the mornings. Both things I'd stopped counting how many times they woke me up a long time ago (not to mention even the old lady from above asking them to be a bit more considerate about in vain since way we moved in anyways).
And though this baby and me definitely not being into the 3-minutes way of things clocked from foreplay to falling asleep, during the relevant timeframe 'all night' was still be a wee bit exaggerated too, 'mafraid.
Tellingly she also didn't mention us waking her up, but just her being unable to sleep.
Now despite the house itself, contrary to the doors inside the apts., being built quite solid, I'm aware, if you listen closely, you'll be able hearing it no doubt. Just like loads of other noises, incl. stereos, tvs, kitchens, bathrooms, and also planes and cars outside.
Which is why my educated guess would be the problem being probly more the nature of the sounds than the actual volume.
Or, after I had apologised politely, declaring it hadn't been our intent to cause her discomfort (even true), as Baby put it with an innocent smile, 'Perhaps she'd need 3 earplugs: 2 for up and one for below.'
