Hiding from people you don't want to see

Is this just me or has anyone else done this as I feel like it is me... this has happened quite a bit and when it does happens I feel silly and annoyed with myself ...

I pulled into a car park the other day and I had a sinking bad feeling in my stomach that a car I spotted was that of my ex in laws... i decided to then hide in my car until the car had gone... I waited quite a long time.. in which I told myself repeatedly that this was silly ... I should be strong and not worry ... but those chats did not work with myself and hiding seemed a better option...

After a while the owner of the car did turn up and it was my ex in laws... I felt relieved that I had hid...

This is the trouble with living in a small town where your ex in laws live... there is no chance that things would ever be okay between us which makes these situations very difficult and avoiding like hiding is better than confrontation...
