And again. As a teenager, I practically lived in combat trousers, but as an adult, smart trousers for women don't have real pockets, or have them sewn up, and even most jeans for women aren't loose any more and often just have pretend pockets. I just end up taking a bag everywhere. The only thing that's always immediately on my person is my mobile phone. The bag that comes to work with me also contains: Pocket 1 Purse and keys. My current keyring is a teeny-weeny Swiss Army Knife which has a small and completely legal blade, a nail file the end of which is a screwdriver, a teeny-weeny pair of scissors, a pen, a small light, and a folding USB memory stick with mobile firefox on it. Pocket 2 My blue badge, and as per Tom's request of however long ago it was, a bit of paper for emergency personnel which has a list of my medications, my 'normal' symptoms and a couple of contact numbers. Pocket 3Medication, tampax, RADAR key, and some sort of sugary snack. Main bag Knitting (usually a sock), USB stick/mp3 player and earphones, small hairbrush, small notepad and pen. I think I've used all of those things at or on the way to/from work at some point in the last few months, except the RADAR key and the emergency details.
