I've been wondering for a while if native English speakers will always give contextual cues or clarify before using an exclusive we or if it's assumed that the interlocutor will pick it up automatically.
For example, if I were to recount a story in the past (to someone I knows me well enough to know who I lived with in Shanghai) and say something like "When we lived in Shanghai, we used to often go to a nearby park". Would it sound weird if I didn't explicitly convey that the we refers to me and the person I lived with back then? Or is it normal to just assume that the person can use prior knowledge (not from this particular conversation) to infer that that we excludes them.
In my own native language (French), we have an indefinite pronoun that I'd generally use on and not really need to specify who I'm talking about before using it in casual conversation.
