Imagine it is your birthday which you might be in your 20's in this story. I just made up some random age. You have been living with Paul ever since you two have started dating. You wake up looking excited. You, "What should I wear for my birthday today? I know Paul is surprising me with something, I just know it!" You try to go in the kitchen and try to make yourself something to eat. You, "That's weird I can't find Paul. Paul probably got up really early and made me breakfast isn't he sweet." So, you look around the kitchen and you don't see any breakfast made for you there wasn't even any made in the fridge. You, "It looks like Paul didn't make me any breakfast. Oh, I forgot that Paul can't cook but, he at least could've made an attempt. No, an attempt would have burned the whole house down. I'll just eat some cereal." So, after you made breakfast you tried to look for Paul.

You, "I should probably wake him up since it is my birthday. But, Paul would probably hate me for waking him up. Well, after I brush my teeth I will just see if he is up then, if he is not up then, I'll just wait until he wakes up." So, after you brushed your teeth you tried to find Paul in his bedroom but, you couldn't find him. You, "That's weird I can't find Paul anywhere. I wonder where he is at." Then you see a note on Paul's bed that said, 'Go out in the backyard. So, you went in the backyard and you saw Paul with a diamond ring down on one knee. Paul, "(Your name) will you marry me?" You looked around and saw rose petals on the ground and you had to think for a little but before you made a decision. You, "Yes, I will marry you!" Then, Paul put the ring on your finger. Paul, "Now, you are Mrs. McCartney ." Then you hugged Paul and kissed him. You, "Thank you for the best birthday!" Paul, "But, your birthday just started." You, "I know but, you proposing to me is better than any birthday gift that I will get."

Imagine the guy and girl in the picture is you and Paul.
I'm sorry that this imagine was so, short.
