Arvin clearly saw the number 3 transforming into a 2. Seeing this a frown appeared on his face…
'What does that mean?' Arvin asked Loki.
{The number 2 is a term used to define quantity.} Loki said.
'…'
{You have studied math right? Why are you asking this question?} Loki asked.
'I am asking why the number 3 turned into 2?' Arvin asked while gnashing his teeth.
{Oh that... I don't know. Maybe this has a timer on it or something like that… you know if you forgot to close it on time then it would close itself automatically.} Loki said.
'That makes sense…' Arvin said.
Then to confirm the hypothesis of Loki, Arvin waited another minute to see if the number changes again. Arvin needed to confirm that this was actually the number represented. And he couldn't be more right about anything else. The number 2 on the safe didn't change into 1 even after two minutes passed by.
