Non-immediate relative, someone you see about once a year on average. Not really close but relations always cordial. Don't live nearby.
Person has had an operation to remove a tumour. Not really sure of the grisly details/whether the cancer is really curable or not, or even of how much the patient knows.
I wanted to send a card or something just to kind of show intra-family solidarity. Is this the sort of thing that people do? If so, what on earth do you say - 'chin up'? etc?
Thanks in advance.
