I loved my grandfather on my mother's side dearly and we were very close. Looking back I suppose he would behave slightly oddly, 
although I never really noticed, after all, I was very young.
He
 was a man of habit. In the morning, if it were a winter's day, he would fetch coal and kindling wood for the fire and arrange them in the hearth in preparation for the 
evening. He would conduct his chores around the three meals in the day 
which my grandmother prepared for him, perhaps visit the shopping centre
 there in Huyton, Liverpool and then he and my grandmother would watch 
television after the fire had been lit. They would drink tea from a 
teapot, with three biscuits and then later coffee prepared with hot 
milk. Occasionally the two of them would drink shandy prepared with only a half a can of lager between them.
But there is nothing peculiar about this. Some of his
 ideas might have seemed strange to some people though. He 
would declare that all motorcars ought be banned,  despite the fact that
 
he himself drove (and not because he was concerned about pollution but 
because roads were too crowded in his opinion), he argued for the 
abolition of inflation (which could perhaps be supported by valid arguments but he was unaware of 
them),
 that all communists should be hanged (he would declare, out of the 
blue, that the Russians were very cunning but, nevertheless..) He would 
chuckle to himself 
 'it's a funny old world.' As he pottered around the house.
I think he felt, and quite rightly, that he 
had been dealt a poor hand in life. He could have been a skilled 
engineer, he was very practical and was fascinated by 
industry, the workings of engines and how things were manufactured. He 
succeeded at school and won a scholarship to university but my great 
grand mother insisted that he go and work and bring money home. So, as a
 teenager, he went to Liverpool Docks and found a job as a deck hand. He
 would later become a steward on the Red Star Line of cruise 
ships. He said he almost got a job as a cook but they were only taking 
on cooks with cookery books. It was common to hear a foreman shouting, 
so my grandfather told me, affecting a strong Lancastrian accent 'cooks 
with 
books' at docks because cooks were always in demand.
My grandmother and he were close and held each other 
in high regard but they were not loving. He never gave my grandmother a 
present, he never surprised her. I am guessing that he suffered from depression.
When I was thirteen or fourteen my parents decided for him that he should replace his old blue Ford Escort
 with the Vauxhall Astra that they had been driving for a few years. 
They had made the offer of buying my grandparents a new car a few times 
previously but he had always turned it down. He loved his car and it's 
engine and modern cars are so much more difficult for enthusiasts to 
tinker with. My parents surprised them with the gift of a new car, my 
grandmother was delighted. My grandfather, for fear that the neighbours 
might think that they had been abroad, covered up the GB sticker with 
black tape.
