Someone feels for you, Receiver, and wishes you comfort. Condolences often expresses the Bearer’s heartfelt sympathies for whatever griefs and troubles a Receiver is suffering. Dignified, without the need for romantic or intimate closeness, Condolences is often the only possible response to tragic events, and a simple Thank you serves to thank the donor. Should the Receiver be in desperate straits, Help!, Despair or I need you can be used to communicate this. Of course, Condolences can also be used as an ironic response to a Receiver prone to complaining, in which case an exchange more noted for its silliness than its sentiment may well ensue. My heart bleeds, Whatever, or Aaaaaaaaaa may all come in useful here.
