Friday morning I was surprised by Aubrey showing up in my office . She managed to keep this a secret and did n't accidentally tip me off nor did she resort to asking my adviser for a ride from the airport . Instead she figured out the bus system and got to UNC , where she manged to find the correct building ( without knowing the name of the building ) and then found my office buried deep in the basement . That woman is determined .
