Hi all

In the near future, I am intending to make a journey from Brockley to
East Croydon, to meet a friend coming from Gatwick Airport, and then
bringing him back to Brockley. How do I do this with Oyster?

Do I just exit at East Croydon, then immediately enter again? Will
this give me two separate journeys, or will I confuse it with an OOSI?

There's no OSI at East Croydon, so no possibility of that coming into
play - just exit at East Croydon and then re-enter.

(Also worth noting that OSIs don't generally apply when exiting and then
re-entering the same station/ gateline - e.g. if one were to exit Euston
tube, then re-enter, that would start a new journey - though I'm not sure
how things are configured at say Victoria, London Bridge, Liverpool Street
or other NR termini stations, where one could concievably exit, circulate
and then re-enter as part of an overall rail journey.)

And what would happen if I touched in at Brockley, then did nothing
else before touching out at Brockley an hour later?

If one was to enter Brockley then exit it before the journey timed out,
it'd be charged as a Brockley to Brockley (z2 to z2) journey,

why wouldn't in be two unresolved journeys?

It would be two unresolved journeys, if Brockley conforms to the
charging pattern seen on London Underground. I used to be able to do
Moorgate to Moorgate within the time budget for a Zone 1 fare. That
stopped working about two years ago. I can still do Moorgate to
Liverpool Street in that budget. The relevant rows a
Mon-Fri 04:30-19:00 Mon-Fri from 19:00 & Sat Sunday
In Zone 1 or 2 90 100 110
In zones 1-2/2-3 90 100 110

There are two rows with the same times after some tweaking of times.
The following rule still applies except as given above:
Within 1 zone 70 80 85

The full story is at http://www.tfl.gov.uk/tickets/14872.aspx

OSIs within a station apply at King's Cross St Pancras and between the
two Paddington stations. Available information on Paddington is very
sketchy. I think there is no OSI between Bank and Monument, but there
may be while the Central Line Ticket Office is exit only in the morning
peak. I know of no other stations where there is an OSI between LU
gatelines. It does not work at Liverpool Street, London Bridge or
Victoria.

I hit a new curiosity at Southwark last week. At the west end of the
station, there are 2 gatelines, back to back and a few metres apart.
Leaving that side of Southwark is counted as a Southwark exit and a
Waterloo East [National Rail] entry. I used the facilities on platforms
A/B and re-entered Southwark. Oyster got confused. My onward journey
from Southwark was correctly started, but charged as unstarted on
touching out.

Just for the fun of it, if I were the OP, I might try Now Cross Gate to
Brockley via East Croydon in less than 90 minutes.
The Journey Planner shows doing that via London Bridge in about an hour.
