Although, I would describe myself as an introvert, I'm not shy and can chat to anyone, but I find it a huge effort to make constant small talk. I was at a wedding recently and although I chatted to everyone I needed to, it got to a stage where I was done and just wanted to retreat and was exhausted with it all. Is this my introversion kicking in, am I unusual or does anyone else get like this? The minute I arrived at the wedding, I felt like here we go, I need to 'turn myself on now'!
