Kitty kitty bang bang

It was around 5 this morning that the cat meowed outside my door, since I'd locked him out of the bedroom so as to catch on a bit of good quality sleep, and like an obedient feline that he sometimes is, he didn't bother me up until his five o clock meow, which sounded a bit distressed.

Launching myself out of the bed was a thing of moment when I heard knocks the sound of hammer banging on a door.
That it was not my door was only a momentary relief because the sounds that no doubt came from swift kicks seemed to reverberate throughout the building.

The fact that it was dead silent, magnified by the unbearable cold that the sounds seemed stark and almost menacing.

The cat appeared to have been terrified by these alien sounds and made a dash for my bed on which he still sleeps.

Now the sounds in questions did emanate from the banging of a door, my neighbour's door and before I could get alarmed a voice which was undoubtedly my neighbours screamed out the name of her son..well, I say scream but she was rather polite if only loud because apparently her son slept indoors while she banged at the door outside at five in the bloody morning.

So many questions.
Like why was she out at that ghastly time leaving her son at home?
Did she leave last night or did she leave early morning?
Perhaps she went for a jog in the middle of the night or at four (gasps) and expected her seven year old to stay up and let her in, the moment she knocked.
Improbable theories or maybe probable. I thought of letting her in, but didn't want her to feel embarrassed. I mean I'd be mighty ashamed if I knew that I'd roused the neighbours with a racket, so I let her be.
I'd decided to invite her in if the situation didn't improve in the next hour or so, but suddenly it was silent and I thought all was well.

A few short hours later I was out and about, making up for my no work out days with long walks (not brisk. The doctor advised me against anything brisk) and saw a gaggle of people outside her door tinkering with the locks.
Apparently a locksmith and maybe some people from the landlords family that rented her the house.

As I'd guessed, my neighbour did look embarrassed at seeing me and tried to subtly back away inside her house, and I pretended to not have seen her either, why make it awkward for someone?

All the commotion has now died down, the locks have changed, I don't know what difference did that make?

Perhaps she didn't have an extra key, or that she forgot to carry her key, or maybe there's only one key.
I don't know, except that this morning started with a bang and a terrified cat.
