I might be getting this all wrong?
My newish neighbour has just told me that she has a severe nut allergy ,throat closes ,can't breathe etc...
I said " Oh ,goodness sorry, and I've been sending your children over with cakes and biscuits not realizing! you must have an Epi pen right?"
"No" she said " "I just drink half a bottle of Piriton"
For a life threatening allergy ...is that enough?
