forgive and forget

it is a very common advice that friends give to one another as a reason to move on and start something new..
but is it as easy to forgive and forget as it is said..
to forgive one another we must let go of all anger and the feeling of revenge...
so once those feelings have been left behind the next step is to forget...
but can something really be forgotten...i mean it does happen in the subconcious mind but to really forget the pain you've been through...
something could be forgotten in a blink of an eye but is it possible to forget the truth??
it is a challenge to face the truth and facts of life itself but once you've faced it could it ever be forgotten..??
is it easier to fogive or forget??
forgive=let go
forget=vanish
which is easier??
as for me it is easier to forgive but really really hard to forget..
it is a reality that humans are created equally so we equally make mistakes
so if a mistake is done...so what?if God can forgive me why can't i forgive other people 'let bygones be bygones'
but all this is a way of learning to survive life and all its flaws..not forgetting an expirience to compleating the journey through life..as it has been said 'once bitten,twice shy'
