My deepest condolences on all the losses posted here.
DataX, it is absolutely normal (and expected IMO) to grieve differently over the loss of any loved ones.
Two of my former classmates passed away this year. I’m very sad about both, of course, but one I’m sad and angry (she died of heart failure waaaaay too young), the other I’m sad but chucking about because he was always the funny guy in school that I had great times with.
