I'm with you, in a store one ear bud in loud enough to block some stuff out, but one ear free so my hyper-vigilance is appeased. But at work (when allowed) or home, both on.

Even then... Was sitting in a room with 6-7 people and someone remarked I was the only one without a device in my hands.

That is what my ”research" indicated, no phones to be open to conversation, I'd much prefer quiet phone time. :) Somehow always on the wrong side

From that link: "construct an ArrayList from Calendar.SATURDAY and pass it to putExtra()"
