background; we'v been here nearly 3yrs, say 'hello' to this neighbour an older lady,she sent us a congratulations card when dc3 born recently, I thanked her and we spoke a little, exchanged Christmas cards, I happen to know she's had a life-threatening illness as she's a patient at my work and my colleague had her notes open on screen
I did NOT open them myself
she gets collected by her friend or taxi every day to go somewhere she has a walking frame
SO; the other day she put a card through the door saying sorry shes not seen us to talk to for some time and how lovely we all are esp the dc's and explaining how ill she is and all she does is goes to chemo daily and that its rare to see such a lovely family 
just the tone of it struck me that maybe she's saying she won't see them grow up 
sorry if iv offended anyone by putting this in the wrong place id just like some perspective please, what do I do or say now? X
