Would you call this being two faced?

I have 2 separate neighbors that do not like each other, so when im talking to neighbor #1, neighbor # 2 name always comes up then negative comments (but true) ones start spewing . I add to the conversation by adding my own negative comments about them. The next day or whenever i see neighbor #2 and we end up talking and the whole scenario is repeated except for now we are talking negatively about #1. Is this being two faced?, By the way i do not like either neighbor and do not socialize much even though we have known each other for years.
