a single bottle of wine turns into a HUGE hangover (i.e last saturday morning)..

.. although it was part of my experiment "how cheap a bottle of wine is actually drinkable without complaint?"

..i've subsequently found out the answer is above 1€ 50 for a litre

or, of course, the other Daily Mail variants;
‘young people today…’
‘bring back the birch…’
‘these people who…’
‘living off our taxes…’
‘national service would sort them out…’

"Of course, there were no mobile phones then".

"Of course, you didn't have the internet then".

When travelling, I used to take every opportunity to get a drink; then it changed to something to eat; then to catch up on some sleep; now it's to go to the toilet.
