I've been so busy posting on other threads, haven't popped in here. But I have a tray of freshly baked cheese muffins ... 
I had been thinking about starting a 'happiness thread' but then remembered ... there is one, in that kitchen!
This made me really happy yesterday - I was in Tesco looking for something on a shelf when a boisterous child of about 10 or 11 or so bumped into me in his clumsy efforts to locate the peanut butter. Simultaneously I noticed that he had Down's Syndrome and also had difficulties with co-ordination, and that he had his younger sister with him, and when I looked at her, she made eye contact and gave me the most, imploring, appealing, knowing look ever that said "Please be gentle with my brother". I stepped aside, helped them find the peanut butter (mum was bringing up the rear) and was rewarded with two gorgeous smiles. A happiness moment.
