Hi, ABV
You might be thinking why I should write a letter when I am working with you sitting in same corner. This is because not all can be expressed directly with spoken words. Though we are working for past 6 months, I still remember the first day I saw you when your voice attracted me. Sincerely I am impressed with your intelligence and hence think about you always and talk about the same with everyone who comes in my way.
With the good impression, I came with an invitation from my side to come for dinner tonight. I am sure you might not have expected this and might not be ready to come for dinner. I do not compel that you should have the same expressions for me. So just, let me know what you have in your heart. I would wait for your reply with pleasure.
Yours always
