Should I look into this?

Yaya was chatting with me during bath as usual. She was obviously very happy that she was one of those two kids being picked for the past two days to get a "field trip" to the older kids class to play for a little while. When being asked what she did in her own room, she said that she played in the blocks area, all by herself. I then asked why alone, here's her answer"because i am new in this school, no one wants to play with me for now, but if i stay longer and they get to know me, eventually there will be someone playing with me.." First, i was so surprised to hear this from her, like the word "eventually" etc, then, i began to worry, is it a problem that i need to talk to the teacher about? She seems happy everyday so far, but i can hardly imagine or believe that no kid wants to play with her. "She is a girl who most kids would like to get close to.." that's the comment we got at the old school.
