When we were in Sahagunj, where Dunlop had their factory, we'd travel every other week to Cal to visit Arup's parents. Often, the whole 3-hour-or-so-journey would be by car but sometimes we'd take the local train and then a taxi from Howrah station to Dover Road.
Whenever we were on the go, I'd mostly have the kids VERY close to me. - Yes, both of them! - Mini propped up in one arm and Bozo perched on one knee. Sometime he'd slide off onto the seat, but still keeping pressed to me, his hand clutching my knee...
Well, I did say 'mostly'. If we were by ourselves, no other Dunlopian travelling with us, for him to talk to, Arup would have Bozo on his knees and talk to him. If Subir (Sengupta, Subir Kaka) was travelling with us, Mini would sleep in his arms - and do unspeakable things to him.
I was in the habit of talking to them all the time if they were close by, and getting them to respond. They'd be wonder-struck by the most mundane of things. "Look at that tree. How BIG it is!" "Watch out! There's another train going in the opposite direction, flashing by us." "That's Howrah Bridge. Why do you think it's there?" (Bozo's answer? "So people don't have to get wet if they want to cross the river.") "That yellow car's a taxi!" ('Tah-sheeee!' Bozo'd say.) And his favourite was the mini-bus. They were all brown in those days. Our Mini was a late talker (and did she make up for that!) so she'd just chortle and chuckle and gurgle and bounce up and down on my knee when she began to sit there. Each time we saw a mini-bus, there was much excitement.
On retrospect, I doubt if they knew why it was a mini-bus. Obviously, they only associated it with our Mini. Maybe they thought it belonged to Mini. Or maybe they decided it was the name of the bus - one bus that mysteriously appeared all over the place, just because it WAS another Mini, so had to be part of us. Who knows what deductions such little ones make from things we grown-ups take for granted, so don't bother to explain?
One day, Bozo came up with the clincher. I suppose he'd deduced from his learnings at school what a 'bus' was, and what 'mini' meant. So he brilliantly put the two together and on one trip, he shouted out, "Oi to! Oita Bozo-Bus!" "There it is! That's a Bozo-Bus!"
It was one of the usual, larger buses and most pleased he was when we agreed heartily...
And from then it was "Mini-Bus", "Bozo-Bus" all the way home!
