thanksgiving, although it is an act of the verb, but it is not the only action required and, more importantly, needs to be done in good faith. easy to say that thanksgiving is gratitude, heartfelt gratitude. you know that every year in november the fourth thursday, what holiday are you? the united states are of thanksgiving. at that time each year, americans should thank god. of our high school students, we would also like to thank "god", but given our lives this is the "god" - our parents.

i like most people, from small to large the most loved themselves, most worthy of the appreciation of their natural parents is that they both in material or spiritual growth i have played a crucial role, naturally, for their such as days of my high thinking deep sea conditions are taken for granted.

i have a first-hand experience with their parents that they do not talk back, making them less angry with their parents to talk about many hearts, with their "resource sharing", the parent every day, so my "thanksgiving plan" is: let them less angry and more happy, happy at all times. do not say, the results are really marvelous!

previously, the sum of my parents for some bring frivolous unhappy much, and i always strongly insist their position, they have a tense atmosphere will be like a boil water "boiling" up, eventually causing a break up in discord. later, after careful thought, i know that are wrong and should not be as to calm, patience and a lot of parents only. so parents do not want to see me unhappy they prepare to try to implement a set of "thanksgiving program", making their parents at any time to face all broad smiles on their faces, but also repay some of my feelings of parents.

say . one night, sitting in my chair on the idea of the topic, his hands up first. happened to see a mother, she has misunderstood me, saying that does not concentrate on my homework, the. although i feel wronged, but in order to avoid a " war" in order to allow mother not angry, in order to "thanksgiving plans," the success of my "bear", did not explain, and said: "in the future, no longer can." this also because i know that mother's personality: forever for their own opinion "defense." i did not expect that, at this moment, my mind has not the past "quarrel" at the time of the burden, but also very happy and feel the feelings of gratitude are revealing. i did not expect to make is this: not long after, but mother "from warrington" - mimi's a laugh.

how kind, the scheme you good results!in short, let the parents are pleased the method is a kind of thanksgiving. "a good start is half the success," i believe after thanksgiving again or there will be "harvest" of.

thanksgiving is a way, thanksgiving is a realm. only institute of thanksgiving, to get other people's respect and love.
