I found a way to avoid the copying involved in the `super` method defined in the first post. Simply use `invoke`.😋

The updated `call(p::AbstractCitizen)` is now:

```julia
function call(p::AbstractCitizen)
    if p.nationality == "Italian"
        print_with_color(:red, uppercase(p.name), " dove sei ?")
    elseif p.nationality == "UK"
        print_with_color(:red, uppercase(p.name), " where are you ?")
    else
        invoke(call, Tuple{AbstractPerson}, p) # invoke method using parent object
    end
end

```
