I have a few little tiny things that give me a little bit of glee in a slightly passive aggressive way...
For eg... We have some nice cutlery and some not quite so nice. When giving it out at dinner time, I will give the slightly less nice stuff to the person in my family who has annoyed me the most. I'm almost certain nobody has a clue (the differences between nice/not nice are tiny) but I get quiet satisfaction from doing this.
When sending an email to colleagues, I'll add them in the 'To' box in the order of current favourite to least. Again, I'm certain they won't notice but it gives me a little bit of pass agg joy.
Does anyone else do things like this?
