Back In Primary & secondary : Children Quarreling

I Was in my room When I heard children quarreling I
came out n asked what the problem was One of them
said the other took his biro The other said its her biro I
was confused I asked if there was a mark on it;
They said no How u come

take know say na ur own?
They kept quite ok To avoid wahala I brought out a biro
from my bag n gave to one of them, There and then i
remembered My days in primary & secondary school
There was nothing like that Because there was
something we always do like yesterday [Flash back...]
