...and this needs to be solved with a law? Kids feeling left out over something well and truly inconsequentual?
I highly recommend discussing a smartphone pact such as http://waituntil8th.org with fellow parents before anyone in their friend group gets a cell phone.
Do parents actually fall for this drivel?
Moreover just because that laws and regulations are applied inconsistently in the US (and we are talking about Denmark here), does not mean we should completely do away with them.
