What there is to say about Alyssa isn't any different than what you could say of other children her age. With no outstanding characteristics, or a quirky attitude, she faded into the background like many others. Her family is not rich nor poor, she has no siblings to share her surname while her daily routine was as plain as butter on toast; with the exception of maybe being spontaneous of putting jam.
However, when news broke out she indeed held magical abilities her parents were dumbfounded. Coming home to a luscious blooming garden that once laid bare was anything but normal. Reds and blues covered where brown once did, vines sprouting along the guarding fence; tulips dancing in the breeze, and their daughter happily sitting within it all.

Receiving the infamous letter of magic rid the family of words, confusion brewing from their frame, excitement shaking their core. The reality of their daughter a witch.
When neither parents had even considered a world besides their own a letter of acceptance could be taken as a joke, but here they were ready to send her off to Hogwarts.

Alyssa's personality could be considered sweet but snarky. She wouldn't hesitate to help a friend or stranger, but she wouldn't do it without a few jokes to poke. Not classified as lazy, she actually loves to study or explore; taking a huge interest into wildlife or nature. While she may not mind company, she's admitting to enjoying the company of a song bird to a humans.
