I like these letter boxes in front of family homes in Antwerp: they are just so thoughtul & considerate.
The owner is apparently a long term thinker, as this one can be easily re-used as an urn grave when fate comes knocking on your door.
A definite add-on is that its split structure will help you out even in times when complete generations of your family have deceased.
I feel slightly embarrassed having considered myself a long term planner up to now.
‘Room for improvement’ – that’s what my auditor/compliance friends would call it.
