Yes, people see me as scatterbrained, awkward, quirky, odd, but generally intelligent. I notice when people kind of "step back" from me in social situations, and I can only guess it's because I came off as a little weird. (One of my alters is always perceived as outgoing, cheerful, and she does social situations very well...so people think I'm having a really good day or something.) I used to be perceived as emotionally sensitive but not so much anymore. I think I go through fewer emotional swings than I used to, or maybe it's that I just have more time to myself (I can be emotional without anyone to see).
I don't think anyone would suspect DID. Just run of the mill odd.
