It depends on the conversation. How its used. The context of the conversation.
like "Hey wanna go for a beer " "OK!"
Or "Hey sorry about your loss" :( "ok"
or neutral
"wanna grab a bite to eat" "Ok"
Steve I think it all depends on the tone. I don't think that it fits in anyone where as it has it's place in all of them.
