I don't know if there is any physical gift in store...because it might pale in comparison to the graduation ceremony ...and he must have pulled strings to make it coincide with her b'day...don't know if that is possible...but then Alzheimers cannot be cured either...so no big deal there...

So long as Nidhi is happy, I don't think anything else really matters!
