anxiety after social interaction

The preparations for that royal wedding of Prince William and Kate Middleton, the Where's Wally World Record comes about in Dublin, soccer tournament for robots opens in Germany, Volunteers in London raise the understanding cancer of the breast, a human wall was made in Manchester city, and etc are a couple of very impressive news in the previous week. While I've browsed Google, Yahoo, Bing and Wikipedia, I can not find an answer about why. I've examined those sites of Taylor, Martin, Gibson, Fender and even more manufacturers and they also definitely don't discuss it. I can not even find anybody with a guitar online forum that has speculated about why.
