Windows. It was a mixture of utter conviction that if I stood within 3 foot of a window I'd instantly defenestrate myself and that somebody might see me through the dull grey nets.
Water. So no swimming, one trip to the seaside where I was never allowed to do anything but stand ten foot away from the shoreline and look at it, not allowed to lock the bathroom door (only allowed to use it at 5pm Sunday afternoon, shut it under duress and her bellowing at me every five minutes to confirm life), no free sailing trip offered by the school, kept off school when they were planning a pond dipping trip. She'd have had conniptions had she known about the 'Free GCSE revision' trip's actual schedule - horseriding, kayaking, trip in a fishing boat, abseiling down a sea cliff, unclipping and jumping across a ten foot drop over the water to reattach and climbing back up.
What I might say to a teacher or somebody else's parent if I were allowed to be around them. Probably justified, as I might have told them what she did to me regularly.
Having friends. Didn't like that at all. They might have told me what was happening to me indoors was wrong - or told their parents (see above).
Wearing anything red. Or green. Or striped. Or with lace (no lace trimmed socks for me at infant school). Or shiny shoes. Or anything black. Or in primary colours.
