Especially in times of shared confusion, disagreement and public unrest, it is worth considering the communities we all belong to. We may be aware of some of their traits, but do we appreciate how communities function as disparate groups?  This week we welcome Qossay Alsattari to discuss ideas surrounding entry into a community. As we settle into our respective roles, we do not always appreciate the strange times associated with changing or joining a community. How can we be more welcoming to newcomers and what should we observe and respect in the communities we join? Are we able to enact change after joining a new community?
