Spray the love letter with a perfume that makes him/her go mad. It should be really seductive and should make your partner remember you immediately.
Writing poems is a good way of expressing your love, if you are a good writer. If you are an average person use the best possible words to describe your partner’s positive. If you fall short of words, search the web for some good love words and descriptions. Decorate your love letter with good paintings and drawings. Let this be hand made. Let these paintings enlighten on how much you love your partner.
If you fall short of ideas, go to the nearest greeting center and buy a nice card with excellent words for your partner. Read your love letter twice so that you are pointing only to your partner’s positives and not in anyway hurting your partner.
Try to express all the feelings in your own words, because you are the one who knows how important your partner is in your life. So nobody else can write a better letter than you yourself can. Use a very dignified and nice language when you write love letters. Don’t use rubbish and bad words. Praise your partner with good words only. Don’t praise yourself anywhere. Your partner might not like this at all.
Write only about those things which he/she is good at. Don’t keep writing what ever comes to your mind. They will think it is absolutely, only flattering and may not respond to you at all.
Remember you are writing a letter or a mail to your partner. This can be an evidence of love any time in your life. If you don’t want this to be evidence, then better meet in person and express your love.
Your letter should be filled with feelings and the minute your partner reads the letter they should start missing you. This should be the exact reaction of your letter. The minute they receive the letter and read it, the effect should be so high that they should call you immediately or come back to you for a tight kiss or a hug.
