I told both my old aged neighbours that we are renovating our flat so delivery and installation of furniture will cause some noise. They said no problem.
Later I caught the bus with one of them and I told her that she could come for coffee and cake once we are all set.
I got no response from her. I thought maybe she did not hear me so I repeated my sentence. Well no response again

She continued our conversation completely ignoring my informal invite.
If she was not interested she could just say "Don't worry" or "maybe one day" but to completely ignore and not sayanything?
Btw the other old neighbour has invited us many times and she definitely would have replied to a similar invite. On the whole they both like us and give us food items.
Still I feel that I got Swiss rick rolled?
