Why people expect us to remember them even after years?

Arre waah beta bahoot bade ho gaye ho?

arre socho socho??

arre tumhare XYZ Mamaji hai na wo mere PQR lagte hai. Badi jaldi bhool gaye, arre kuch time* pehle hi to ABC k yahaa uss function mei mulakat hui thi..............
*and this kuch time ranges from a few months to few years also

Consider this situation, at some family function you are enjoying with your friends and relatives and suddenly you heard someone calling you. You turned to that direction and found that some close relative calling you, you obligingly goes there and found some uncle or aunt with them and all of sudden above one sided conversation started or better to say your interrogation (your response is mostly yes/no).

And this is the time when you are in situation when you really want to bang your head hard on the wall..........


As in how come you remember each and every person whom you perhaps (or never) had met hardly for few minutes, had some hi, hello, how are you stuff and the talk finished. This happens quite often as there are always some people whom your parents or some relatives want you to meet at some functions. And after years when they meet you at some other function they just pop the question "beta pehchana?? and all that" and you just end up giving expression that comes when in examination hall you realize that its your maths paper and but you studied only Social Studies for last three days....

So friends tell me do you have any solution/suggestion about how to handle this stiuation?
