Weird thing at a funeral

The weirdest thing I have ever saw at a funeral was when a person, not gonna call their name, kissed the dead person in the casket in the mouth. I mean they tongued the dead person as if they were still alive, now that was nasty, weird, scary, and gross. They had been together for 63 years or better. The spouse stated that he had to get one more kiss from his wife because the kiss was so good when she was alive and well. The kiss could not have been the same I guarantee you that because she was dead. The wife was dead what interaction could she possibly have gave back, none. I would not have believed it if I did not see that for myself, but it happened. I did not hear it from someone else’s mouth I actually saw this happen. I could not believe it. I understand a fair well kiss on the cheek or forehead but the mouth that was pure nasty. I did not want to go to another funeral for a while for the fear of not knowing what a person would do next.
