that they are drinking too much - or should I keep quiet?
I've noticed that a good friend is drinking more than she used to. I've not seen her falling-over drunk but she seems to always have a bottle within reach. Having known someone who died from alcohol poisoning I'm worried that she might be heading the same way.
Should I say something to her or not? She's likely to be offended and it might harm our friendship. But I don't want to see her become dependent on alcohol, if she isn't already.
