a little monkey was sitting on a tree. she was bored and she wanted to eat. she got down the tree and looked through the jungle to find a banana of a mango. but there was no fruits and even no tasty leafs. she was upset. she wandered through the jungle and meet her friends - green crocodile and bright parrot. parrot was very hungry too because he also couldn't find anything to eat. they decided to walk together. in a minute they noticed a huge yelow banana lying on the floor. monkey clutched it and at once many hunters with guns run to the glade.
friends started to run away. they ran through the bush and high grass and they saved their lives from the crafty hunters

Источник побед в неповторимом менталитете. Нашу тактику сложно предугадать. Настолько отчаянные поступки, на какие во все времена могла пойти Российская или Советская армия, не мог предположить никто из иностранных завоевателей. Кроме того, Россия зачинщиком этих великих войн никогда не была. Мы всегда только защищались. Народ нашей страны всегда гордился своей родиной и поэтому стоял до конца. Такого патриотизма сейчас наверное уже нет, но в былые годы это позволило нашим предкам отстоять эти земли.
