I get the same reaction. When i'm nervous, i laugh, and people think i'm doing it to be mean, but i'm not. I hate crying infront of everyone, so all my emotions get all messed up and i laugh. I agree that its harder when they have open casket. I always hate that. I usually stay away from the casket. This one funeral i was at was real hard, it was open casket, and he was the best elder in the world, and his family are dear friends of mine, well anyways, they stood infront of the casket while there was a line to talk to them. Just to see them grieving and then to see brother vallas hurt me so bad. That was the only time I ever broke down and cried at a funeral. i still cry when i think about it. but anyways, everyone acts differently. My brother passes out at funerals that he's close to the person that died.
sorry bout that...................................
when i went to my grandfathers funeral, i didn't want to talk about it. people come up i haven't seen in years and i would just smile and ask about everything going on their life. i didn't wanna talk to anyone about it. then afterwards i felt so ashamed that i didn't cry because maybe people thought i didn't care. (he was in my top 3 of favorite people list. and i love him so much.) but i cried so many other times besides that. nobody can tell you how to act at those things because you can grieve in any way you want.
Same with me, but i wasn't crying because everyone else in my family was when my grandfather died. And i didn't until some time later. There was a song that we heard on the radio right after and when i heard that two weeks after i just started crying.....
