At different stages of life I heard this word , each one meant differently.
--WHen i was 8 yr old i remember as i was the elder one, i was asked evry time to GROW UP, i.e in compared to my younger brother.Which would emphatically mean dont be mischevious as your younger bro.You aree supposed to be elder,so behave decently.
--When i was in my teens say class 10, i was asked to GROW UP , this time meaning that i should stop playing cricket too much and concentrate on my studies.
-- then the GROW UP when i was in my engineering studies where my parents,relatives, friends all alike meant the same i.e get serious with your future,dont play like a child,BE A MAN, grow up.
Now all this thought dawned on me in a very unlikely place,The BARBER SHOP,as they say SALOON.This happened when the barber who was cutting my hair was a short guy .I dint notice it till i saw his hand moving very slowly. I asked "kya bhai ,form mein nahin ho"...he answered back "nahin! bhai aap bahut bade ho isliye mera haat nahin pahunch raha hai"
In english--WHat happened you seem out form ,for ur hands moving so slowly,
To which he replied--NO boss, you are too big for me, thats why my hands are not reaching your head.
NOw me again-- they were my childhood days when i used to go my barber and he would place a "Plank" on the chair for me to which i have to sit, coz i was too small for the chair.( i know you too sat on planks :)...And now after 27 years, this barber tells me pls lower down or sit a bit low coz the chair is too small for you...
WOW !!! i have grown up.Finally if not my parents but atleast the barber told this,though in diff. context i know, but I am happy to hear the words "YOU HAVE GROWN UP" :)...yaeee...yaeeee
