....we both met on the side walk of the Broad Street, both searching for the Sheldonian Theatre where he was to be a speaker in the inaugural ceremony, and I was to sit on an excruciatingly uncomfortable chair/bench... !!

I can't claim it as an "achievement" - it wasn't!!
I was merely at the right time at the right place...
...last time similar coincidence happened was when I was born :0)
