Hello fans of SRK, Kajol, Rani...
I rewatched Kuch Kuch Hota Hai, and decided to try to translate the letter Anjali is reading at about 1:23:36.
Here is the letter:

Now, this is what I read, followed by what I translated.
I put in bold words I am not sure of.
HINDI:merii pyaarii anjali,
bahut din ho gaye tumne ek khat bhi nahin likhaa
tum thiik to ho naa ?
rifat bhi ko zyaadaa sataa to nahin rahii ?
Anjali
inse hum naye ghar main aao hain, tumhaare paapaa kuchch udaas se rahne lage hai
tumhen bahut yaad karte hain
unkii sehat bhi thiik nahin rahatii
anjali is saal chchhuttiyon men bhi tum ghar nahin aai
tumhaare binaa is havelii men,
na ronk hai na shor aur vaise men bahut
padaad ho gaii hai
ab ghar aa
naauvahaan kya rakhaa hai ?
ENGLISHMy dearest Anjali,
I's been many a days since you haven't written a single letter.
Are you fine or not?
Does Rifat Bi feel better or not?
Anjali since we are in our new home, your dady has become very sad.
You left us so many remembrances
His health is'nt going better
Anjali for these holidays you're not at home
Without you in this mansion,
there are no splendour nor noise, and then many ....
Now when do you come home?
There was is left?
I think I succeeded for most of the lines, but I surely mistook here and there.
It would be nice of you if you could correct my mistakes.
Happy New Year for all the goodwilling people
