Unique

Two day ago I was as usual washing pee tray and suddenly I heard a sound, look out of the window there is a bird outside my toilet window, I continued washing pee tray and this time I heard a whining sound from the bird? I think the bird leg was stuck outside near the window, at that time I don't know how to help so I ask mum to wake up from her afternoon nap and help the bird, before mum came to the toilet another bird fly over from somewhere and seem like helping the bird and see him trying to push the bird but the bird still whining in pain and for awhile later the helping bird fly away? Mum ad me saw everything and our conclusion the bird can't help so fly away. I went over to open the window bit by bit and mum try to help the bird and the bird know I am opening the window and it stick it head into our window looking at me, seem like telling me to help, at this time mum use her finger and pull the bird leg out and the bird finally free and it fly away. After the bird fly away me and mum was talking about the other bird cos it fly away so we are thinking cos the bird can't help so fly away and let the bird 至生自灭. Suddenly heard a sound again and I saw a bird fly back and look into our window seem like looking for the whining for help bird... After looking around for awhile it fly away. Me and mum know the bird fly back maybe found some ideal of helping the bird but can't find the bird so look around and this is the first time I saw two bird stick their head into our window, one is looking for help and the other is check if I had caught the bird into my house. This little encounter touch my heart. Little animal are better then some human being.
