salutation(priya behena, priya rekha etc)

tum kesi ho? ghar par sab kese hai? asha hai sab kushal-mangal honge. mujhe yaha janne ko mila ki tum padhai me bilkul dhyan nai de rhi.. mera toh tumse yaha kehna hai ki jag jao, isse pehle der ho jaye. tumhari parikshayen bas kuch hi dino me prarambh ho jayenge, isliye parikshya ki taiyari abhi se sunischit kar lo. 

dekho behen, ek baar jo samay beet jaye, baad me wapis nehi ata. yadi tum iska arth samajh jaoge, toh avasya tum apne-ap hi padhne beth jaoge.tv dekhna, khelna ye sab baad me bhi ho sakta hai, parantu exam baad me nai ho sakta. 

isliye padhai man lagakar karo. .aasha hai tum meri baaton ka dhyan rakhogi, aur avashya safalta prapt karogi.maa-pitaji ko mera pranam dena aur mera aashirvaad to sadev tumhare sath hai

tumhari,
