Nothing too incriminating, I don't think... certainly not in light of some of the recent threads 
Just a short exchange of 15 or so messages sent over a couple of weeks arranging a night out between a group of colleagues.
All fairly innocuous "where are we going?" "who else is coming?" "hope you're enjoying the sun" type texts.
But then he ends one (a bit out of the blue) with "it'll be really nice to see you, again x" and another with "ok, see you soon, sweetie x"
Her responses to these are very simple, "great, see you then x" type responses.
The end of the exchange is that he says no one else is going, after all, but suggests they "go out anyway... x" and she declines citing potential workplace gossip as the reason.
Anything to be read into it, or not?
