Air lock in the water bed again

We have an airlock .
Its a complete mystery to me how a water bed can fill up with air not three weeks since we last " bled" the air out of it and filled it full of hot water again .
And what a carry on that proved to be ....The hose has to be dragged up from the yard ( cleaned first ) , the nozzle attachement located next ( a half day job , not mine I hasten to add ) , the bed itself stripped , and wait for it , the cats removed ( and kept out of the room , no mean feat when a hose has to run from bedroom to bathroom along the upper landing ).
I remember it well .
I had a funny feeling about that event and sat it out downstairs until my presence was requested .
By the time I was called up D was hopping from room to room as cats watched in fury at being ousted from the warmth of their own personal heated bed , trying to gain entry each time he opened the door .
The bathroom was in a state of some disarray , the basin taps having a hose attachment in their general vicinity , applied with the aid of several elastic bands ( post office issue ) and squirting water up the mosaic mirrors , across the " I can see myself in the roll top bath if I wish to mirror " in a generous fountain , anywhere in fact but down the hose and along the pipe and into the water bed outlet . The Ikea bathmat was drenched and several of the towels had seen better days .

I survey the scene and remind him the taps configuration didn't look like this last time . ( talk about stating the bleedin' obvious )

Suffice to say after a certain amount of pressure is applied to the taps and attachments ( rather than my neck ) the problem is remedied and a vast quantity of hot water is relayed to the bed . Always a tricky moment working out whether the hose will deliver the water onto or into the mattress ....... ?? By now all attempts to keep cats out is at an end and there is an audience of four ..... cute faces with whiskers all watching intently , the ocasional squabble breaking out over who gets closest to the action .
An equally large amount of air is pumped out .

And with this in mind I find it hard to understand where this new air has arrived from , though I have my theories , relating to nocturnal male flatulence , which are heartily rejected .

It is the cougar all over again .
When travelling to Kirkharle in search of Kendal Mint Cake for Amelia , my stepdaughter,
this afternoon a creature stepped onto the road and I became convinced it was a cougar ( or a lynx possibly ) but D simply gave me a suspicious glance when I mentioned this . He often does not know how to take me . I suppose it could have been a rabbit .

Flatulence aside however , male , female or feline , it is a mystery how a bed which was completely bled of air suddenly fills up again and sprouts visible rugby balls at various points , causing the bed to splosh alarmingly during the night even when a small cat lands or takes off .

No wonder my dreams are so full of this and that and even in my waking hours I can honestly say nothing seems to make much sense .
Maybe I have an air lock in my brain ?
