[Sundae]

I've recently been craving pink grapefruit juice.
I get ever so thirsty at work, especially on bakery, and there is always juice available at breakfast in the canteen. It's subsidised, but in general I never have any credit on my key fob in the last ten days of the month, so I drink chilled water and sit and lust impotently at the carton of pink grapefruit.

No doubt I'll buy some on payday and my unholy obsession with it will abate.
I feel the same about cold fizzy drinks some months.
It's what you can't have that appeals the most...
Oddly this doesn't apply to alcohol, probably because although I want it, it's more that I mustn't have it, rather than that it's out of reach for practical reasons.
