I met two women at work and we became good friends and regularly went out. One of them invited her best friend to join us - she’s lovely and I like her.
Just sometimes I wish it could be the three of us. As we have to dictate the conversation to include us all (whereas the three of us have a big thing in common and know lots of the same people).
Just for relevance the best friend has a boyfriend and many friends so she’s not lonely or doesn’t go out much.
