To me it's easier to talk to older people because it is a given that being old past a given threshold generally lowers your social status in modern societies and they tend to be more lonely on average. We have all met someone who is old and is desperate to establish contact about anything. This means that their whole demeanor is inviting conversation, establishing eye contact and smiling and all that

I happily "take the bait" cause I am a quite patient person but sadly, people who are lonely have such an urge to talking that they are totally incapable of listening. I consider myself a good listener, competent at signaling than what they are talking about is actually going through but a lot of the time they might as well be talking to a tree.
