who clearly never learned the concept of how to behave in public. Though this is a common feature on my commute, because I've been "enjoying" her music for the last 20 min, it's grating on my nerves. Is it that she really likes to share? Does she need a sense of validation that her music is okay? Is she running a social experiment on peoples breaking points? I'll never know...
