There is solution!
I’ve heard of these "sounding by sovka" grandmothers. The form of sorrow sounded as follows: "The New Year was waiting for a branch and a mandarine to kiss, and now it is boring, any day - buy and eat."
Addict your grandmother to truffles, for example (real, not from the mouth front). And once a year for the new year, prepare a meal from it. Let him grieve for the remaining 364 days.
