No, the keychain had a single R, unlike Raghav's bracelet that is RR. The envelope of the thank-you note had RR, but the thank-you note was signed R.
By the way, the thank-you note written by Ramaswami included the Hindi words "āpake lie choṭā sā" in Devanāgarī alphabet, but by the time Raghav had to read Farhad's bhūla bhūla poem, he had difficulty reading Hindi (i.e. Devanāgarī). I wonder if alcohol abuse can reverse literacy?
