Today I shouted at mum.I was tired and hot and we had just come back from a "wheelchair walk". Mum has developed a very irritating laugh/giggle/chuckle. She does it all the time and for no obvious reason. It went something like this--- I am struggling to get the wheelchair into the garden as mum likes to sit there for a while. "chuckle chuckle" "laugh laugh" "WHY ARE YOU LAUGHING AT ME? I AM STRUGGLING TO GET THE WHEELCHAIR OUT AND YOU JUST LAUGH AT ME" "Sorry but I have to laugh at something" I hate myself!
