I can't whistle, no matter how hard I try. Perhaps it's just as well. When I was around four or five I remember my late grandmother trying to explain to me why I shouldn't whistle. Looking back I think she was trying to explain that only lesbians whistled. It made as much sense then as it does now - none at all.
Bear can't whistle either. DH has done his best to teach bear but without any luck. Bear, however, has learned that he can make a sort of whistling noise by sucking air in. He has been off school today as they enforce a strict 48 rule so I have listened to the sound of bear almost whistling all day. It has been tough.
Fortunately bear is in school tomorrow. Hopefully I can start the pre-Christmas clean, sort out the doctors and generally catch up. At least my knee is a lot better.
