I have very good sense of smell, and so many memories are evoked by specific smells. Lavender is my grannys underwear and jumper drawers as they always had lavender bags made from her own lavender. Baking bread is of course my mothers baking day and having cold meat and bubble and squeak for dinner as she was too busy baking to do any fancy meal, but we would have a lovely (to us ) fancy jam tart , where she would put thin pastry on pyrex plate and then twisted pastry ropes to divide up the plate and it would have strawberry jam in 2 quarters and lemon curd (both home made) on the other quarters. We enjoyed choosing whether to have all red, all yellow , or a mix of both in our slice. My husband once said it was like living with the gestapo, as he arrived home from a journey of about 50 miles and I said "Oh can I have a polo too please?" and he replied I ate the last one before I set off home. How can you tell? My son had asthma and we moved to make sure he was in fresh air and of course we never smoke and am very against it. So one day he was about 14 I said to him "It is no good coming here if you are going to mix with boys who are all smoking" He said but I didnt smoke, and I said I know that etc so unfortunately for him I could tell if he had been eating sweets or smoking or whatever. There were negative effects for me too, as having teenage lads standing nearby at school who obviously thought that if you splash on far too much horrible Brut or Lynx or something , that meant you didnt need to wash at all!! Uggh!! So every day I can enjoy the many pleasant smells and I always dry my clothes outside. Whatever so called fresheners they advertise, they wont have me a s a customer. That lovely fresh outdoor smell is the one I love.
