The key with gifts is to give her something that will keep her thinking about you long after you are gone. If she is thinking about you she wont be thinking about no one else.
Great gift idea.
Buy a cheap, pocket mirror that women usually carry for make up purposes. Put it open in a box and close it. Put a note on it that reads "Open to find my soul!" When she opens it she will see a reflection of herself and you will be the king for the month. Cause she will have the most envied thing all girls want, a great story to make her friends jealous and envious.
PS. To make it even better sometime this week make a quick mention how you think it really means a lot when a person puts thought in effort in a gift, cause it shows you really cared a lot to go through so much effort instead of spending money on a gift a million other people have. Make the comment quick and then move on trust me she will store it away. This will instensify your gift by a million times.
PSS-the greatest game isnt what you really think it what they think you think.
