Five of Karl's classmates attended his birthday party, some where accompanied by their parents. I noticed that his classmates are bigger and taller than my son, but I learned that most of them are already turning 8 this year unlike Karl who just turned 7.
Anyway, a day after the party, Karl still received gifts from some of his classmates who were not able to attend the occasion. One even sent him a letter about their friendship and I was so overwhelmed with it. I hope Karl mingles well with his classmates.
