Hey Koen,
My 2 cents worth; I personally had only a negative response from a neighbour, who - excuse my saying so - wasn't a real brain surgeon. All my friends and family thought it was wonderful. They had all met Steve and saw how lovely he was, and knew I would be fine. And hey, if it would go wrong, I would go back, it was that simple.
Why some people get grumpy, irritated, jealous and so on... Maybe because they see somebody else having the guts to go beyond borders that they (the people who don't move) have set for themselves and can't cross.
I don't think that we as a person are brought up to be different and brilliant. We are in general brought up to conform and fade into the background. So you stay where you are and that's it, sort of. When then people say 'Hey, we going to move to another country', I think that deep down inside, it does appeal to some smouldering feelings, and not being able to give in to their own adventurous feelings might make them feel frustrated.
Now how to handle that? If they get upset with you.... Tell them you'll miss them too, of course! Tell them you love them heaps and will call often. Try to understand their being upset - they're entitled to! And the louder they scream, the bigger the hug is that you're going to give them. Tell them it's great to know how much they love you and will miss you.
Apart from that... you (you in general) don't have to 'agree'. You can also 'take what they say in as information'.
What do you think?
Ireen.
