I live in an area that was hit by floods last week. There's an extreme sadness in the community at the moment and I know various people who've lost everything. Most people round here do.
MILs colleague got flooded and lost everything downstairs. Even worse they've lost so much equity in their house they have had to pull out a sale, and their buyer understandably pulled out too.
He returned to work today and MIL said to him "It could be worse, it's only water, it's not like it's bombs." Well needless to say he wasn't happy and had a whinge to their boss, and MIL got a bit of a bollocking about being insensitive. She can't see what she did wrong. DH seems to agree with her.
AIBU to think that it's a twatty thing to say "it could be worse, you could be in (insert situation)" to someone suffering and that actually it's all relative when it comes to any situation - what might be a disaster to me may not be a disaster to you?
