I mostly feel that people should be more selective about who and how they open up to in general in life. There's a lot to talk about that's not your past experiences with depression, and those don't need to be talked about to 99% of people, and discussing them too early is an easy way to burn bridges before they're even built.

I definitely talk to my coworkers about what I did this weekend, or travel, or the weather (I'm halfway around the world from my home country, so comparing the weather is a constant topic of conversation). I have a coworker I carpool with and we talk some about how I'm settling in to life here. But, I will never discuss my history of mental illness with any of these people. At best I will make a vague allusion to seasonal blues.
