That to me is way worse than what you claimed to be inappropriate.

Because?

[adam12]

For me, the 'but' negates the congratulations.

[jacquesm]

Yes, that was the situation we already had. So if there is to be a 'but' then this is the more accurate one.

The very best thing would be to either say nothing or to congratulate without any reservations.
