If you've arranged to see someone tomorrow and they send you a general text in the morning with 'see you tomorrow xxxxx' at the end, do you assume from this that you won't hear from them again until you see them tomorrow? I assumed that but clearly I was wrong and they are funny with me now as I didn't call or message in between that and seeing them I'm not very good at picking up on subtle stuff like this! For some reason, to me, unless it's to change plans or just check all still ok, 'see you tomorrow' implies the end of the conversation until then.
