When you quarreled with your beloved, you may feel very detestable, right?! And at times you don't know how to say sorry and make it up with your beloved. So, I would like to give you an idea what you can do to soften heart of your girlfriend/boyfriend.
Order personal billboard! It may contain your or your beloved's face (that she or he would pay attention to it for sure) and sweet words about your love! Say how strongly you love your beloved and ask her/his pardon! The billboard is better to be fixed near his/her house or work!
IMHO your beloved will be greatly pleased and touched having seen such personal message from you!
