When the plane was about to land, Leo still did not want to leave from sitting on my lap so I had to grab him by the armpits before standing up. While Leo was still flailing about to no avail, I simply lifted him all the way up before throwing him back to his own seat, lifting up the blinds to prevent the other from coming back without walking around the aisles.
Although I could not manage to see Leo's expression after throwing him back to his seat, I knew that he would pout at me again once the plane landed. Unfortunately, the flight attendants obviously does not care about my misery, since they immediately removed the blinds after realizing that they were still reaised, stating that they needed to be stowed before landing, which made me feel irritated.
