hey, enjoy it, brother!
just speak to one or two people at the end.
if everyone is shy, then take a coffee after the liturgy and sit down at the same table with some other people.
make eye contact and smile a few times.
after half an hour, the curiosity will overcome them and someone will then actually speak to you!
(tip from my experience at an armenian coffee hour. don't think they had many non armenian visitors.
they improved since and now host several wider orthodox events!)
i am sure someone will speak dutch, or if not then maybe english. just hang around until they warm to you.
(some shy people are like little kids. to get to know little kids, i interact with them for a long time from a safe distance,
and then after i get to play with them.)
praying for you
