A selection of headlines from stories in the news. They use English in a way that you might think is intended to confuse but it's all perfectly clear yo the native speaker.
This isn't from a newspaper, it's from the topical TV programme "The Wright Stuff". One of their discussion topics was called "Bitter Tweet Sympathies", which is a play on the song title ""Bitter Sweet Symphony", by the Verve. The topic was to discuss whether it is OK to send condolences via Twitter.
If something is "bitter sweet" it evokes feelings of pleasure and pain.
