Hi @DirtyBeetie
DS2 is very shy and has social anxiety. He and I worked out a programme for him to overcome it and it definitely helped. I'll share it.
Every day go for a 10 minute walk somewhere there are people but not crowds.
Day 1 - just glance up and look at people's heads when they walk past.
Day 2 - briefly look into their eyes (fraction of a second)
Day 3 - meet their eyes and smile
Day 4 - meet their eyes, smile and say hi.
The very important aspect of this is that you doing this is the end goal. There is no goal of getting any recognition from them. They are free to ignore you, grunt, walk past, cross the street and you haven;t failed at all. You have succeeded.
Day 5
Do the same as day 4 but when someone ignores you analyse 10 reasons why e.g. maybe they're shy too. Or they;re habving a bad day or they;re in a real hurry etc. Especially do this if you know the person and they weren;t friendly. This trains you not to take it personally. Make sure you get to 10 good reasons why people aren;t always responsive.
Day 6 - Same as Day 5 but in an appropriate social situation just say 'Hi' and ask a simple open-ended question to three people you meet. E.g. at a social event say, 'Hi, how do you know X (the host)?' Plan a simple question.
Again, your goal is not for them to respond in any way - it's just to fulfil your aim of saying that line. If you do, you have succeeded. You're not responsible for other people's reactions. (At one party DS did this and a girl was really bitchy to him. Obviously this upset him a lot. But he'd done what he set out to do. At other events, he's had a brilliant time through just doing this. Now he knows it's possible.)
At your new job, practise just saying: 'Hi, I'm Beetie, the new X. It's my first day.' If they have any social skills, they'll tell you their name and what they do. If they don't, help them out and ask.
If people are friendly and invite you to join them for lunch or on a work social event, you only need to do two things. Smile and say, 'Thanks.' Nothing more. Then go along with them. You don't have to be the life and soul.
