He is out of date

while he was busy living

the world changed

too quickly

in the click of a mouse

the ding of a smart phone

the future happened

he used to know the present

but then got left behind

the world moved on without him

he can't handle the truth

he can't catch up

he is now a Senior

in the school of yesterday

he is past his expiration date

turning hard and stale

used goods on a markdown table

with few days left

of value.
