Way to go to mis-interpret that: random people as in 'people that you simply come in contact with during everyday life'.
It's not as if any of those people had a way of controlling who they came in contact with. Life is built up out of tons of coincidences and who you know is rarely a matter of deliberation, far more often it is random chance that causes you to know one person and not to know another.
Random is the Russian I sat next to on a flight to NYC and never talked to / connected with again.
Random is NOT the guy I went to school with in Moscow and would fly back to russia for a wedding for.
The OP didn't say which group he'd classify his friends in, but if he thought it was pertinent enough to list them, than he had a close enough relationship to warrant listing them. Cause when OPM/FBI find out that you went to school for a year in Moscow and you didn't list any acquiescence's, they'll raise some flags and find what you are hiding.
