Why on earth is my 23 year old sister overly obsessed with Taylor Lautner?

Honestly I am very annoyed by thisbfigure actor Taylor Lautner my younger sister will not shut up about this dude. I literally just roll my eyes and yell at my sister to stop talking about that dude. At first I didn't give much tough my sister ask me if I could give her thebtwilight books I was planning on donating to goodwill all I tough was nice my sister found a new hobby in reading then she kept on watching twilight movies didn't think much of it until I went into her room wow her room is full of Taylor Lautner posters. Now my sister will not shut up about Taylor Lautner. Just outbof nowhere she's overly obsessed about this character.
