He's in year 5 and will be 10 in a few weeks. He announced on the way home in the car that a weird thing happened in school today. A girl had asked him out, or rather, her friends asked him on her behalf as she was too shy. He's clearly flattered and agreed, although he has no idea what this involves, except that now he has a 'girlfriend'.
Should I be worried? He's definitely at the curious/finding out stage of things (has asked me a few choice questions recently).
What do I say to him? My lovely boy is growing up way too fast for my liking!
