Mary O'Connor and her husband Bobby Hughes had been in Letterkenny for a couple of days,when they decided they would spend the afternoon at Rathmullan beach.
Bobby is a diabetic（糖尿病患者）and needs to take insulin（胰岛素）regularly.On that morning,he had checked his blood sugar levels,which were fine.He ate breakfast without any difficulty.However,an unlucky incident happened.Mary said,"Ten minutes after we were there he just completely went down.It was just scary and it was so sudden.I think the really severe heat was a key factor,but it reflected how quickly things could change. "
A few moments later,two women from Derry noticed that and rapidly came over.One called Sara who also was a similar patient recognized straight away what was going on.She said,"I had a bottle of glucose gel（葡萄糖凝胶） that I kept for emergencies and I was rubbing it onto Bobby's gums."
Mary said,"Some young lifeguards were able to call an ambulance and another lady called Emma,who was a nurse,stopped by to help us as well.Eventually we got him into the ambulance and I started to shake from the shock of it all.A nice man,Liam McAteer,whose mum owns the pub in Rathmullan,offered to drive me to the hospital and even took me back again to get my car. " Mary said that the staff at the Letterkenny hospital were so brilliant in treating Bobby that he was able to be discharged later that day at 6：30 pm.
She said that while there was much more drama in their holiday than she thought there would be,she was very touched by the kind strangers.Mary continued,"It is wonderful to know there are good people and we are both so grateful for all help that they gave us. "
