Actually, I think she avoids Twitter, and I’ll tell you why. Her dad is famous. If Nerissa tries to go on Twitter, all she gets are requests for pics of her dad, questions about her dad, etc. Even if she makes up a name and identity, she gets ferreted out. Her dad advises against bothering with most social media, so Niss mostly texts and Skypes or FaceTimes her friends and that’s about it.
She might have Instagram though.
