The quick answer to this question is probably far too much!
Asking a woman to share what is in her handbag is like asking her what colour underwear she is wearing, it is a very personal thing. That said, I don’t mind sharing.
So, in my handbag I have my purse, a bottle of water, my husband’s warfarin book, an umbrella, a cheque book, a notepad, 2 pens, my husband’s Epipen, a couple of sanitary items, small packet of tissues, an inhaler, paracetamol for my husband – yeah, I’m wondering too why I have lots of his stuff in there! – housekeys, Glucose tablets and a Mars Bar. The latter two things are for emergency use just in case I have a hypo when I am out and about.
