Interpreting Something from Almost Nothing

This poem is basically an apology for doing something that the speaker thinks might upset someone else. I am assuming the speaker is a husband, brother, or father who ate his wife's/sister's/daughter's plums that they had stored in the ice box. I assume this relationship between the speaker and the owner of the plums is a good relationship because the apology does not seem to have much fear in it just a little regret. The hidden meaning of this poem could be that even if you do not feel remorse for what you have done you should always apologize to keep the peace between you and your friends, peers and loved ones.

here goes:

I  constantly
take
your money
every day

I will not
work ever
again 'cause the
welfare

It is nice
to be free
I am sorry
about the money.
