1. does the way they do things portray their internal personality?
For Mallory? Yep. What you see is what’s inside.
2. do they do things that conform to the norm?
Is it normal to be a serial killer who sometimes studies phycology, is obsessed with sweets and who may or may not be a little insane? Didn’t think so.
3. do they follow trends or do their own thing?
Depends on the trend, tbh.
4. are they up-to-date on the internet fads?
Nope!
5. do they portray their personality intentionally or let people figure it out on their own?
Depends on whether she likes you or not. If she does, she’ll let you figure it out for yourself, if she doesn’t, she’ll portray her personality intentionally.
