Celebrating my last Teacher's Day

It's the day that all of us teachers(and students)look forward to -
it's the day to show our love and appreciation to all our teachers...
and for teachers, it's a welcome to be showered with little tokens -
that say very big Thank-yous and I-love-yous and a chance to repay...

This last Teacher's Day was passed with mixed feelings, though:
happy that it's going to be my last two and a half months,
but truly sad, too, at the thought of what i'm going to miss -
and that i'll be leaving all the warm smiles behind...
and that heart-warming feeling when a child you've often reprimanded
marches up to you, gift in hand, to say,"Happy Teacher's Day, Teacher."

But, i've learnt that, whatever it is, life has to go on -
and that friends are like the pebbles and boulders that one passes
on one's way to the sea: some do follow one all the way -
but others are left behind, never to meet again...

Which one are you, my dear little friends, i wonder?
the boulders or the pebbles, i oft times wonder...
Just which one are you, my special little friend -
the pebble or the boulder, i just wonder...
