I don't blame elders that act like kids. They may have their reason
Elders that do like kids may not have time to play or act when they were still young of which is a process you must follow
Some elders that act like young may believe in acting like a kid is better than being claiming old
Some elders don't want to get old again
Some elders are just like that
There are some elders that are born being fool and never change till they grow old
While some are like that since their young age
