This scenario is NOT the opposite of the previous one where the snowflake was trying to engage the codger in conversation by banging on the seat, poking the purse, and asking her name. In this case, the codger was doing nothing to engage the snowflake, was in fact minding her own business, when the snowflake interrupted. In both cases, the snowflakes interrupted.
I'm on Team Codger for this one too. The fact that the grandma didn't say anything says a lot about her restraint because she had every right, imo, to tell snowey to mind her own business.
