The rather annoying chatty bird in the lift

I mentioned a little while back that the women in this office building seem to like to talk. To random people. When I first started working here people talked to me in the elevator. Small talk basically, "I like your outfit" or "It's awfully hot today". But it threw me for a loop. At my old job, we had the whole building so you knew the person who was standing next to you, or at least knew they worked for the same company.

So, what inspired these women to talk to some strange person they never met and tell her that they liked her outfit? It's not a bad thing, in fact it's quite friendly, but I never know when I step into the elevator if I'm going to have a deep conversation, or a quiet ride down.
