it was a funny ending

Here was the scene:
HY was playing with my cell phone on one side of the sofa. EY's attention was caught by the beep beep sound of the cell phone. EY crawled over to reach for the phone with no fear. HY raised phone over her head, passed it to the other hand, dropped it back down then lifted it up again. She got very good at avoiding EY's grabbing attacks. At the same time, she "ahh-- ahh!" at EY. EY could only use one hand to try to get the phone so she was not as fast as HY. After a few unsuccessful attempts, EY decided to sit down right in front of HY and used both of the hands - one to block HY's receiving hand, and the other one to reach for the phone. This time, she got to the phone fast. Once she got a hold of the phone, she pulled it out of HY's hand - she was that strong, ohh yeah!

During the whole time, HY was tensed and frustrated. EY was happy that she succeeded. She flipped the phone back and couldn't hold her giggling in. I couldn't hold my laughs any neither because they were just fun to watch. I laughed with EY. HY heard both of us laughing, so, she laughed, too. She forgot that she lost the phone and she thought it must be funny because mama and sister were both laughing. I just cracked up by HY. She was so cute. She was laughing after losing her toy! Babies, happy babies!
