The day that went

I am on doggy duty which probably explains why I was suddenly MIA last night but the interesting or rather odd turn of events that led to that sudden situation last night were confusing at most.
I wasn't sure of the exact date when the neighbour would be traveling and a day before she informed me that yesterday would be it and gave me the low down as to how and where things were kept in her house and other mutt related info.
I was half expecting that before leaving I'd get perhaps a prompt, a message, a phone call or at least some semblance of hint that they were leaving and that that the canines were now in my care.
It was while watching a tv series last night when the clock had struck nine that I began to grow concerned since there was not a sound nor a peep to be heard which meant the dogs were alone in the house and that no one had been back.
What does that mean?
That no one had taken the dogs out for an evening walk, nor had they been fed and no one had informed me about it.
Naturally I'd assumed that the neighbours would come back before leaving for the airport, knock on my door, tell me they're about to leave etc etc, but apparently they left with their luggage in the morning and went directly to the airport after work without coming back and doing the needful.
So basically it was guesswork and I was left with the puzzle and finally ten minutes after nine I let myself in the house and the dogs were delighted and half sad to see someone other than their family, but they know me well and took it in their stride and soon after they'd had their evening walk and a meal after which they were cleaned and put to bed.
I found myself getting upset almost fuming about this situation because before entering the house I'd called and messaged numerous times to ascertain whether or not they'd be coming back because it was just so sudden and they near vanished without a trace and left it up to my discretion to do as I please.
I mean a word of knowledge that hey, we're leaving , the dogs have not had their walk or meal etc, would have been helpful but NO!

Anyway the dogs are cleaned, walked and fed and now I teach them a couple new tricks.

But seriously what do you make of this odd behaviour?
