I hope this doesn't sound harsh but if you are not very close, keep it low key, My husband died from secondary brain tumours just over 18 months ago, and at one point near the end, he commented that he felt like a star turn at the circus. People were popping up from all over to see him and were incredibly jolly and reminiscing. They meant well but it did grind him down a bit. Do what you feel is right in your particular circumstance and I send you love, its not nice. Understatement I know.♥
Ps keep in touch with your Aunt as well.
