Oh it's so easy to laugh at the older generation as they attempt to grapple with the ever-changing technology of the present day: never knowing quite how to operate 'the interwebs', or peering down at a phone from behind reading glasses exclaiming, "well, how am I supposed to understand how this bloody thing works" in a manner befitting Victor Meldrew at his most negative.

Enjoy...
