The Trio in DH (holding hands)

1) Scream and shriek loudly and tell them you're speaking Mermish.
2) Always speak in a British accent (if you're not from the UK)
3) Relate everything they say to the Harry Potter বই & movies.
4) Crowd their ইনবক্স with HP-related emails, and make sure the subject are misleading.
5) Give them Harry Potter merchandise for their birthday and demand they treasure it forever.
6) Pretend আপনি can do magic.
7) Yell "Crucio!" অথবা "Avada Kedavra!" if they insult Harry Potter.
8) If you're late for something, blame it on your broken Time Turner.
9) Sort every person আপনি meet into one of the Hogwarts houses....
