You were Harry Potter's older sister named Rosalind Potter and the same age as the Weasley Twins, Fred Weasley and George Weasley. You were in sixth year, and you and Fred were really curious about the Mirror of Erised.

So, one night off curfew, you and Fred stole your brother Harry's Invisibility Cloak and hid under it, venturing into the corridors of Hogwarts. After a few minutes, you entered a room and saw the Mirror of Erised.

You took off the Invisibility Cloak and giggled, and so did Fred, and the two of you ran to the mirror and stood in front of it. After a few seconds, something appeared in the mirror, and it was...

You and Fred, married with two children, aged 1 year and 4 months, and you looked like you were 18.

You and Fred were shocked to see this, even though you secretly loved each other and were afraid to say it out of fear.
