Warning! Alcohol may cause eyestrain!

This week, as you may have noticed, is a full week of Gems, all resulting from a single game of Trivial Pursuit. You may also recall that said activity was assisted - for Julie, at least - the consumption of a glass or two of wine. A half-decent Shiraz, as I recall.
To begin with, any oddity was purely down to my wife's generally wonderful nature. After a while, however, the wine did begin to take effect. Not that Julie was slurring her words. No, it was more that Julie's brain was actually being slurred.The mouth was fine; I could understand every single word that was spoken. It was just when you put the words together as Julie did that your own brain began slurring in sympathy...

Apparently, this quirky little epithet meant that Julie's eyelids were feeling heavy as a result of the wine she had drunk.
Yes, love. It's totally obvious, now that you mention it. -.-
