March,30th is my birthday,but it is not on weekends.So my boyfriend want to celebrate my birthday in advance.
He have been planning this birthday for a long time.He wants to give me a surprise.Yesterday he told me we would go to beach at 10:30 at night on friday,because he would have test between 8 o'clock and 10 o'clock.
I thought it was to late and i was a little fear of going out so late.My boyfiend was angry about this,he thought i was not trust him and i was afraid of staying with him alone.I was not meaning that. I known what he did for me.I trust on him.
Today we had lunch together.I fought he was not full of energy,he must not sleep well at night.He will have test in the night.I hope he can do a better job about his test.I don't want he is so tired.
I promised to go out with him to celebrate my birthday at night.I am looking forward this trip.Say happy birthday to myself,say thank you to my boyfriend.
