Raising hands

Kedaar was playing today after dinner with Lego blocks. I was checking laptop for something. Suddenly Kedaar asked, "mummy I need your help to put the lego blocks". I told him to try by himself first and then call me if he has questions. Then immediately he raised his hands and looked at me. When I asked him, what he is doing "he said I am raising hand because I need help". Apparently in school, the kids have to raise if kids need any immediate help in doing their activity. I think as the teacher have to deal with around 15-20kids, they have this rule.
It was so cute. Kedaar surprises us with some interesting act every day.
