I have a lovely friend who I’ve known for many years. Unfortunately, at the beginning of our friendship, I failed to realise that the reason she is about 3 stone lighter than me is because she eats about 3 times less than I do.
Whenever we go out together, we invariably share a sandwich or some sort of main course between us. Fine, I can deal with this.
Things get a bit more tricky when it comes to sharing cake. I love my cake but, eager to not reveal myself as the greedy cake lover I am, I can share cake (and then go home and eat more).
But things hit a new low today. Three of us met for coffee and cake. Long-standing friend suggested sharing one piece of cake between the three of us, other friend seemed to think this was a great idea, and all I could do was agree 
One piece between three of us! Traumatised. And hungry.
