Telling People About Using A Mobility Aid

Any advice on how to tell friends you’re gonna start using a mobility aid (specifically a cane). What sort of reactions and questions to prepare for (I am fine with questions for the most part)? Telling in a group? I’m considering telling a big group to avoid awkwardness when they first see me with a cane but I know others I either can’t contact or won’t care (not in like a rude way but are just like really accepting). Is this a good plan? Ways to word telling people etc. Also a bit more random do any of you have names for your mobility aids? I’m interested
