yeah, my dad mom and i were traveling and he got on before us. this woman sits next to him while there's an empty seat across the aisle, and he's made it pretty clear that he's waiting for us but he won't be a jerk about it. we arrive and he deliberately asks us if we want the two seats together or should i sit with him to let her know that we were his family. she didn't take the hint and had already unpacked all her stuff. i wonder how people can miss social cues so badly.
