This weekend. In the kitchen. I'm cooking, and behind me I'm aware of Tall Daughter fiddling with her hair.
TD: Mum, this funny looking hairband you bought for me is too big.
Me: (looking to check what she's talking about). Um, that's because it's not a hairband. It's one of the wires from my bra, it came loose so I took it out.
Oh. The. Shame.
