Is It Jealousy? Poem by Asit Kumar Sanyal

My parents reached yesterday
sis today morning
she was lying next to me on the bed
we both pretending to be asleep
a message came in her mobile
she sat up
checked me, sleeping or not
and silently went to Kamu
to feed her accumulated honey
My heart started beating in pairs
I too sat up.
it was 11.15 pm
could not sit for long time
laid down
unknowingly I sat up again
and it continued
I couldn't understand... why this is happening?
she is enjoying her own partner
and I am taking tension for nothing
is it jealousy?
or I am in love?
I couldn't sleep at all
till my sis came back.
