I think the losing stuff thing really depends on a person’s disposition in public. I have an older sister who’s like this so when we were younger i took it upon myself to minding her and her things whenever we have to do lots of shopping or when we are out and about in public. I don’t think it’s about being scatter brained but more of being lax and being too comfortable in public. This rarely happens to me though because I’m hyper vigilant and aware when in public and sometimes i envy others that can just be so relaxed like that.
