Meets Sid and Joan when out (7)

I believe the answer is:

adjoins

'meets' is the definition.
(adjoining is a kind of meeting)

'sid and joan when out' is the wordplay.
'and' means one lot of letters go next to another.
'when out' indicates an anagram (out can mean incorrect or inaccurate).
'sid' after 'joan' is 'joansid'.
'joansid' is an anagram of 'ADJOINS'.

(Another definition for adjoins that I've seen is " Lies adjacent to".)

I've seen this clue in The Globe and Mail.
