Character stocktake

My one and only god brother emailed me and told me that he needed some help for his master's assignment... he requested some of his friends (including me) to put in state his character... he asked us to do a character stocktake...
at first i thought, this will be easy, cos i knew him since i was 13 yrears old.. which means i've know him for abt 12years.... but honestly, upon reflections, i cannot think of much, cos he has changed for the past 12 years... there has been a lot of changes... but the very typical character description, for example - dependable, humourous, responsible, etc are so.. ermmm normal. i realised i don't really know him for one reason for another... everytime i talked to him, he has been very nice and willing to listen to me.. talk abt issues / matters that I faced... whenever i asked him how is he, he will briefly go through and end the topic.. to be frank, i don't think he has opened much of his thoughts and feelings to me as his god sister... i think this status is just in favour as a name, but not really how much he understands me....
last year he bought me a present, he bought me a chain with a dolphin pendant.. and frankly, i dun think i actually wore anything stuff that has a dolphin shaped on it.. not to mention accessories.. i remember he gave me a pair of dolphin earrings for one of my birthdays, maybe he just remembered that i seem to like dolphins from the reaction i gave from that pair of earrings i gues... it was so long ago.. it was during my first year of NUS? well.. i've not worn anything that has a dolphin imprinted accessories since then.. i guess he din realised thar i've grown out of it and i didn't really try to know him better over the years.. and the thing is that it has been so hard to get him out or even have a decent chat with himn that i really dun know how am i suppose to understand him better.. i guess, i should have tried harder.. cos i feel that i could have done much better... a bit sad.. feeling very guilty.. and extremely upset that i've not understood him very well... i mean i should.. but i've not...
and i realised, i've not really paid much attention to the people around to really understand them much better, especially when i view them close to me..

New Year Resolution: Make efforts to know my close friends better, paying attention the nitty gritty details too...

Well, i hope i can do it man... friends, please help me k? i'll need your help in order to understand you better...
