We first became aware of what sounded like a lot of hammering & drilling overhead (renovations, maybe)? Then, a series of rapid thump-thump-thumps -- not so much the pitter-patter of little feet as perhaps a small herd of elephants?? -- sometimes louder, sometimes more muffled. We also noticed a pattern: first thing in the morning, then again in the late afternoon (beginning around 3:10 p.m., to be exact), and on & off throughout the evening, most days.
We've decided that it must be a couple of small children creating all or most of the noise -- who else could be that energetic that consistently, right?? (As further proof, we've also heard childish voices from the balcony above ours, during nice weather -- not to mention faint wails overhead some evenings -- clearly, someone who is NOT happy to be informed that it's bedtime!) We've concluded that the mid-afternoon noise must signal their arrival home from school/daycare. We think we encountered the likely culprits in the elevator once: a weary-looking mother with two children -- a boy who looked to be about 6-8 and a little girl several years younger.
We have debated whether to knock on the door and complain/ask (nicely -- at first, anyway...!) if they could tone things down a bit. So far, we haven't (although we still might). Some days we notice it/it bothers us more or less than others. We figure that eventually, energetic young children turn into lethargic teenagers staring at screens, who will move off the couch only under protest. ;)
That day is still several years away, however...! We know that kids will be kids, and we are willing to cut people SOME slack. At the same time, we believe we are entitled to the peaceful enjoyment of OUR unit too. Right? :p
