Hi,
This year is my first xmas being with someone who has a child. He is 12 / nearly 13 and is obsessed with cricket so as a sort of token present (we’ve only be together 3 months) I’ve brought his son cricket world stars top trumps...He’s a nice kid not a brat or anything. I’m just wondering will that be too young for him? Is he going to look at it and think “I’m not 6!!”
Thanks!
