We have some couple friends that we have known for around 10 years. Over the years we've all moved house a few times. During a discussion with my OH today we realised that although we have hosted the other couple many times for drinks/lunch/dinner/ parties in all our houses (obv not much the last year thanks to covid) we have only been to their house once, for a birthday party. Whenever they suggest a catch up they either want to meet out somewhere or they say they are happy to come to us. Their house is a similar size to ours, nicely decorated and they are tidy people so I doubt they aren't inviting because of the house.
We get on well and enjoy their company but starting to wonder if it's odd that the invitations are never reciprocated.
Anyone else have friends like this?
