Luckily for Link, Luke's also very used to men who don't talk much. Uncle Owen hadn't always been big on using words either.

Unlike when Luke was a child though, he's more okay with silence now and when he can't think of anything else to say he just gets lost in his own head for a while. Which leads to him quietly sitting over in his section playing with little balls of light because the dazzling light cantrip has become his habitual fidget toy these days.

But it does mean their time can pass in silence, at least for a little while.
