Exposure therapy kind of works?

Just got back from a conference and trade show in the IT industry and spent 3 full days with coworkers and reps from companies all over the UK for various IT solutions and products. It was an exhausting 3 days from all the walking and talking but I found myself going from being a bag of nerves to genuinely enjoying a conversation with a stranger about a common interest (nerdy computer stuff).

I also got to know my coworkers better and had a proper decent set of conversations with them. Is this what I’ve been missing out on?
