Does it seem young people give short answers whereas us older people give longer drawn out ones?

Yea. Us old people use two hands at a big keyboard and a giant monitor. And we think THIS may be the very last thing we say, ever. So we try to stretch it and throw in our life history.

Young people probably use smartphones, type with one hand while doing something else and pick their comments from dropdown boxes. And since they are young probably figure they have a lifetime to say whatever else they want to say.
