My recent KIP experience was in a lovely local cafe where they sell local/organic foods and there is a corner with toys and books for kids. Love this place.
Anyway, nobody said a word or stared even though I performed the following strange activities: joined a ball of yarn by felting ends together (using jasmine tea), shaped sock's toe on dpns, grafted it, ca-a-arefully checked that the socks match, weaved in ends, pulled out 2 more pairs of socks, put them on the table and took a picture, after which packed them in individual ziplocks, wrote notes and stick them in with the socks.
I also might have hummed something or sung quietly in my language...
I really wanted to make an obvious joke that nobody talks to crazy people -- that's why I had no comments --, but instead I want to say that it felt oh, so good to be able to do all that and nobody at that place minded one bit.
