Here it is what I consider a good example of an ironic situation.
You wake up not too much late on Sunday morning, as both you and your husband have to work on your pc....
While you are having breakfast, you think that it could be nice going to the public library, after lunch, and work there until dinner time. Then, you could also have dinner in a pub of the city centre. Sounds good!
So, to optimize your time, you have a very short lunch, you get dressed and you run out of your flat.
You arrive at the public library (which is full, despite it's Sunday), looking for the only two seats remained (obviously, they are located at different tables, so you won't be sitting together) and start working.
After only one our (which is just the minimum time needed to concentrate), a polite female voice says that "the library will be closing in 10 minutes"....
Ops: you forgot that today the winter time-table started!
so, no afternoon in the library....
.... no dinner in a pub....
.... just came back home!
