๐ Explanation
ใใในใใงใใ is used to express that something is a duty, a social expectation, or a strong piece of advice based on common sense.
It is attached to the dictionary form of verbs. For the verb ใใ (to do), both ใใในใ and ใในใ are acceptable.
The negative form is ใในใใงใฏใชใ, meaning 'should not'.
Note that this is stronger than ใใใปใใใใ, which is more like a personal suggestion.
