A few weeks ago I spent five hours in total helping my friend get rid of her kids head lice.
They were riddled and it took forever to comb them through. 
She is a bit clueless and I advised her to comb every few days to ensure everything had gone.
I've got them for a sleepover tonight, she's just dropped them off and said 'oh they've got lice again and I've not treated them yet' WTF!
My DD hasn't had them yet but it's odds on she will now. She has very long hair and I know it will be a nightmare.
What I should have done is grown a pair and told her to take them home. But as she's going out I just bit my lip!
I'm such a mug am I not?
