Some One's Birthday!?

For yur imformation, there is some one in our Backsitterz group is going to his/her 15th birthday! XD Well i dun wanna say names right here and also right now. XP It is for you all to guess! Well this is a little bit of tips abt our birthday boy/girl. XP

- He/She is always smiling, you can never see him having a sad face.
- That person doesnt like showing off his hair.
- He/She is an Ace level leader.
- He/She is always wearing a hat.
- He/She is called Mei Mei.

Very easy question, I bet everyone of you can answer it pretty quick by just looking at the second tip. XD Okay that person's birthday will be on 21th December. He/She would have problely called some of you all abt his birthday party.

Pity him/her la... Join his birthday party. Even knw some of you all are not close to him/her but as yur a Backsitterz, you will be qualify to join his/her birthday party. But is BEST that you call him/her and ask him/her whether you will be coming or not.

Remember 21th December is a very special day for our birthday Backsitterz member! XD
