I love surprises, and on my birthday, my girlfriend waited until the last minute to give me something. I honestly thought she had forgot.  
I love a good surprise like anyone else; however, when my girlfriend waited until 8 pm on my birthday to tell me happy birthday and give me a present, I was caught off guard. I thought she had forgot.

Maybe she did and remembered last minute. You should ask her!

She remembered but was trying to draw it out to make me think that she had forgot. I should have known because I made her wait until 10 pm on her birthday.

Next year I would just forget her birthday all together!
