Run it under the hot tap for a minute. Put a rubber band around the lid. Whack it a few times with a knife around the edge and break the seal.
But it is always a good thing to occasionally ask a man to help, as Mum would tell us.
I needed to do this the other night – I was flying home from a work trip interstate and asked for a wine from the drink trolley. I then struggled to open the damn thing. So I had to, reluctantly, ask the man next to me to open it for me. He beamed, and I think he felt a little needed at that point.
Maybe Mum is right. We really do need to occasionally ask a man to help. My experience on the plane also explains why the next line of this lesson was always: ‘it makes them feel better, love’.
