i was 21 when i left, so im pretty fluent in Dutch (my grandfather would say "vloeibaar")
vader was asking if you by any chance came from a hamlet called Drachten
i asked if that was one of the eleven cities in a ice scating tour they put on when it gets called enough (cultural thing, i dont know if you would know it or not)
then i mentioned there is a small lake between you and me right now, but i dont see you scating across that one
finally i mentioned the hamlet i was born and grew up in, about 35 miles from where vader lives, and low and behold, thats where his son in law is from
