Delivery of life

I heard the postman sneaking into my garden again
His mail was boring as usual my friend
but he brings a bit of life to the sceen you know
He carries these gifts often and then has to go
Never getting to see the people opening them
Some are expensive, others cheap as hem
Like those he delivers to outwardly
He gets to know you like this inwardly
With these little glances into your life
To assume you're a horder or a shopaholic wife or well loved, sometimes famous firefighting marcial.
Sometimes though, he delivers more than the parcel.
