Dear Ishita,
Happy 19th Birthday! Who knew you would make it this far?! I'm so lucky to have you as a best friend and sister. Whether it's doing silly things on vacation, going on long drives and having gossip sessions, or just talking to you on the phone at night, life with you is just better. I hope you have the best birthday ever and I can't wait to celebrate with you! I hope you like your gifts hehe :)
