We have the same old joke overhere, so I don't think it has anything to do with the history of your country. I'm also not telling you not to bother. I'm simply stating that I've sofar never experienced an announced soft to be effectively there at the indicated time. (Now have you?). What's more: it is still 20 May overhere, so your joke doesn't apply yet and they may still surprise us (or announce a delay).
