sharing

If youre sharing picture(s) on your phone with two people do you hold it out in the middle so both can see or to just one at a time so they can see it more close up? Also do you show the same person first each time or switch the order?

a and b are talking to c and c is like let me show you my pics. holds up phone so a can see but b cant. then when a is done shows b. next pic, repeats shows a first then b.

or does c hold it in the middle each time so both a and b can see?
