@ElizabethMainwaring I also used the typewriter to make pictures, and later the Amstrad daisywheel printer. I noticed that the full stop tended to emboss the paper, so that you could feel it on the other side; so I once tried to use it to write Braille, having learned about it at school. Of course, the whole thing had to be written back to front.
I kept wearing my shoes without socks, because I liked how it felt, and we were made to do so at school when walking from the classroom to the assembly hall for PE; but my mum wouldn't let me try them on like that when buying them.
I liked recording; for nostalgia I recently bought the "Usborne Cassette Recorder book", which I didn't have as a child, and felt a pang as I saw things I should have tried to do, such as putting a microphone inside an open umbrella to record wildlife.
I loved activities for which I had to be blindfolded: taste things while holding my nose, guess objects by feel, point at someone making a sound, find out which parts of my body could feel whether they were being poked with two pencils or one. Most of these were from science books (the last one being about nerve endings), but then I started inventing sillier ones: guess which socks someone was putting on me, get someone to paint my toenails, and when they were dry to put shoes on me, so I would then spend as long as I could guessing what colour they were. In the summer, I once got someone to blindfold me and spin me round in the garden, and leave me sitting in a chair, to see if I could work out which way I was facing simply from what I could hear; and also challenged myself to stay like that as long as I could. I managed an hour and a bit before I got bored. I was easy to entertain!
