Sure I can tell you beforehand when I can come. But let me have a look at what is happening too in Europe.
Things don't look at the moment. It's very uncertain times here. I hope you understand my feelings about this. I told you before about it.
It doesn't mean I don't want to come to see you. I want to come to see you :-)
But now I need to wait and see a bit before I can make a plan.
