I socialize well if it is a workplace scenario and/or I have a specific topic I'm supposed to cover. When I worked retail, I was selling products, so I had a topic. As an educational advisor, I'm disseminating information, so it's relatively easy. If they keep interrupting me though, because they're anxious, then I tend to get "stimmy" and ask them to wait, let me finish my spiel, then they can ask anything they might still have questions on. Normally, this works out well.
Among friends or in the general public, I am good to order a hot chocolate or drink, unless there is good music. Music, particularly with a nice beat, that can break me of the Apsieishness. Otherwise, I don't say a word all night.
