I don't find this to be a huge deal but just to add to this, here's the part I just went through:
"ill be over real soon, okay?" "okay, thanks tomoko" "im here!" "got home safe!"
Those messages came in one after the other with no delay. So to bdorfman's point, that felt like it might be a bug? Again I don't really mind, just want to make sure things are working the way you expect!
