emotional

Danielle is happy and playing with Devon, having fun. Then out of the blue she comes down stairs balling her eyes out wanting a hug, of course she gets all the hugs she wants. When I ask what is wrong I get ” I miss my Nintendo DS” but she lost the DS over a year ago. Why is she so sad about it now, then after she pulls herself together and starts to go back to her room she says she may just cry a little longer (just really feels like crying)?
