my nanny won't stop staring at me!!!!!!!!

I live with my nanny... and even when I'm sitting minding my own business I can see her in the corner of my eye just looking at me. and I just get so cringed out... she sometimes comes into my face (joking around) asking questions and stuff and just stares at me till I give her an answer.. and it makes me feel so uncorftamble... and I'm like .. right go away now... and she just laughs and continues to do it.. I don't want to be rude because she is my nanny .. but fk jeez talk about feeling uncortable @@,
