My Dad just heard from my Mum, she said she was at Heathrow for 5 hours, most of the time spent on the roof because there are just too many people there. I am not sure but I think she was kidding about the roof. She is staying with my Aunt and Uncle (her sister) and I don't think she is too upset about it! She doesn't get to spend enough time with them so I am actually kind of glad that she is being "forced" to stay for a while! She expects to get home sometime maybe Wednesday or Thursday.
