I let Ioannis laugh his heart out if that was what it takes to calm him down. This was a better outcome than the situation turning into a fight, a soap opera or a cold war. I was also worried that such negative emotions will affect the children so him laughing in amusement is the best outcome so far.
It took him a minute or two to stop laughing. He had to stop because his stomach started to harden due to the lack of air, making him feel slightly uncomfortable. I looked at him and shook my head. I asked sarcastically, "Are you done? Do you have to laugh so much until you can't breathe?"
Ioannis looked at me, still trying to normalize his breathing. He then answered, "Don't look at me like that or I will end up laughing again." It was my turn to roll my eyes at him, eliciting another bout of giggles from him.
