Question: why do guys can easily forget things.. in a very short time... why girls having hard time doing that easy???? 

Answer: Well really they dont forget they just choose to not think about it and but it out of their minds. Us women tend to hold on to things that we feel we will need to know at a later date. Men never forget they just choose not to think really.
