I am not sure I can do just three of these but I’ll give it a go …

1. People making noise – I seem to have sensitive hearing, especially at work and any noise that annoys me can start me off on a bit of a tirade. These noises can include: people eating; noisy wrappers; scraping plates; sniffing, breathing. Pretty much just people in general!
2. Lack of common sense – I am a pretty logical person (well I like to think so anyway) so it astounds me that there are people out there who lack any common sense whatsoever. Like recently I was sitting on the bus. The bus stopped at a stop to pick up passengers, this woman gets on and proceeds to stand at the front of the bus – which was fine except that another woman gets on at the same stop and she has a pram. Why wouldn’t you let the woman with the pram on first instead of making her push past you?!
3. Bananas – more specifically the smell of bananas (which is weird considering my love of Minions). I may or may not have complained about bananas so much in the office that people leave the room to eat them.
