What i find really frustrating and awkward is when you say good bye at train stations, what is there correct etiquette for it? any other situation you would, kiss, hug shake hangs and say bye, turn away and leave.
Whereas on trains, for some reason you go through the normal goodbye routine but for some reason you have to hang around and wait for the train to actually pull away from the station before the process is complete.
So you sit down on the train and wait for it leave, there is that awkward moment between you both as you dont really know what to do, then as the train pulls out you wave again.
So what i do now is if someone sees me off, ill just say bye get my book out and ignore them, or just drop their bag off say bye and not even bother walking them to the platform.
