Ok so I'll try to be brief with this saga. A mom I met briefly in a dentists waiting room got me to agree to a play date between her 2nd grader and my 4yr old. I thought it was weird but agreed mostly because it caught me off guard and I didn't realize her quiet, small build child was that old. Anyway it's Wednesday and I do not want to continue making them play together. How do I get this across without being a jerk? I want my son to play with kids his own age. Also this woman is creepy weird. I feel sorry for her kid. Who at 7-8 wants to be set up with a 4 yr old stranger to play?
