Sounds Absurd

a)There  once was a person who had 15 children. One day one child got sick 

and died. The following day another child became sick and died. This 

continued on with all his children. By the end of the month all of his 15 

children died.

Someone suggested that he throw a party immediately after

the funeral of the last child to celebrate the stopping of his childrens death. 

Sounds absurd !

R. Akiva had 24,000 Talmidim. All 24,000 Talmidim died. After they all 

died ,we  celebrate Lag Baomer because they stopped dying.

Sounds right?

b) According to most Poskim, the Talmidei R.Akiva did not stop dying

on Lag Baomer. (they hold, they stopped dying on the 34th day)

What's Pshat?
