Dear moon_moon,
My son was taken care by my mun few months ago, but their relationship don't get very well, my mun always lost her temper to him, and my son doesn't like to be taken care by his grandma, (his 心理醫生 also suggest they should not meet often as his grandma affect his temper very much) so he is resently alone at home, my office is very near my home, at lunch time, I will ride my bicycle to my home and buy lunch for my son, and I will go home immerdiately after work to take care him. I know it's not very good to let him alone at home, but I can't find anybody to take care him.
My company have block us to use msn, so I can not use msn at work.
