I was only saying to my DD, a couple of days ago, that I have never been bored.
As a child (born 1967), I lived in a very quiet village with few other children of my age, so I had to entertain myself, my parents would never dream of entertaining me and TV was only on in the evening for the news!
Like others on here, I read a colossal amount (mostly books, but I would get the Beano delivered on a Friday!), I would play the recorder, I would take my dog to the field and play with him for hours. I had imaginary horses and would 'groom' and 'exercise' them, I taught myself to type using an ancient manual typewriter and a Pittman's instruction manual. I built many a den, I would teach myself the names of all the wildflowers and to recognise all the birds. I would build tents in the garden, play with my tortoise and rabbit and clean them out regularly, and I had a tiny patch of the garden allocated to me where I grew sweet peas and stocks!
I played Word Search games, Patience/Clock Patience and Solitaire, washed my dad's car, helped mum peg the washing out, rode my bike and went for walks, picked blackberries in the autumn, chalked hop-scotch on the drive and played that for hours. I played tennis up against the wall, coloured in those books that are now trendy again as stress relieving colouring, wrote stories and poems, played marbles, played on the stilts that my dad made me, played on my roller skates, and even played Monopoly on my own!
I was always happy with my own company and I can, hand on heart, never recall being bored.
Ha! Reading that back, I realise what a great childhood I had!!
