Working on an important problem was a difficult thing which took me out of my comfort zone, but it also took me into the whole late-night-at-university sort of a zone. I was doing a late-nighter with Jeff Wayne's War of the Worlds and other music for company and it was almost fun. It was hard work, though.
A low-light of the remote working was when I had to do some Wi-Fi access in a Starbucks with an Australian girl who blethered her pointless drivel-of-a-conversation at a rate which made me want to turn to her and say "saying it faster won't increase its value, you're still at zero interesting-per-second, even though nobody can possibly listen at the speed at which you're yattering". However, a later highlight of cafe-wi-fi was when I found myself sat next to two beautiful actresses, who were talking about their auditions for West End musicals and singing bits of songs to each other. Then the really gorgeous one got out some sheet music and started sight reading it to her friend. I wanted to thank them both for being so gorgeous before I left... I didn't. That would have been weird.
