Erasing Memories

I regard the movie Eternal sunshine of Spotless Mind as a ridiculous movie which could obviously have been made better by the Director and the scriptwriter except for two things:
1. Kate Winslet (of course ;) )
2. Hunt to find the way of deleting memories of somebody from the mind.
I was just owndering if I could delete memories of someone in a similar fashion by contacting to a doctor, creating memory map and then the erase operation ... simple... isn't??
But, the question is do we really like getting deleted our sweetest memories of that special person in our life? Isn't a treasure that we should always keep with us and feel the smell whenever required??
Now, in the real world what will you do if you want to forget somebody. Here are some options:
1. Deleting his/her number from mobile phone - I don't think it will really work. You will get it again whenever you want.
2. Delete all places of contact where you can see him - In my opinion "out of sight, out of mind" is the best policy and removing this person from GTalk, Orkut, Facebook, LinkedIn and any other social contact place will really help. Joining new communities over Orkut will be of great help.
3. Divert your attention - few tips are below:
a. Start delving deeper to your project work. Work with full motivation and start thinking to improve the process of your daily routine work.
b. Start listening songs and reading books, it will keep you busy for a while.
c. Start more browsing related to various stuffs like PCs, Laptops, Phones, inventions etc. and Wikipedia of course!!
d. Meet old friends and talk to them. Listen their problems (don't tell yours...) and you will find that your problem is very silly.
e. Do some community work. It will help you as well as society.
And then there will be a day, when you will even forget to think that that person had ever existed in your life ... all traces will be washed itself.... forever ... one more thing, when you will start these things, initially you will feel that these thins are not working and it is reminding you more of that person.. but as soon as you will start gaining interest in these things.. they will changed as your higher priortiy and push back the hard memories ... now, when you will see that number which you have never deleted from your phone.. you will think that calling this person is going to cost you a single buck.. and this person is not worth of it!!
