We moved in a year ago, next door to us are a couple with 2 girls. Few weeks after moving i went over with some some chocolates and said hi and general chat outside door step with the man, i even said tell your other half to pop over for a cuppa it would be lovely to meet her. The man has always been polite to us and will acknowledge us however the woman has not once said hi, there have been times when she is in the house and ive gone to drop off their parcel and she has not opened the door instead shes waited for her husband to come home to collect it.
From what i can tell there are no language barriers or health issues from what i can tell. Im not too bothered by it in all honesty as ive got far to much going on in my own life but just out of curiosity im baffaled as to why she is ignoring us.
