Helen的妈妈要过生日了，Helen不知道送给妈妈什么生日礼物。她想给妈妈买件毛衣，但没有足够的钱，她问Ann有什么好的建议吗?请代Ann给Helen回信并阐明以下要点：1.礼物是为了表达情意，它不能用金钱衡量的.2.花钱买礼物还得向父母要钱; 3.个人建议：买束花，再自制一张贺卡送给母亲。
Helen:
I think we neednt buy anything.
The present only for our best wishes and thankness,it can not use money to measure.And if we buy a present ,we should ask our parents to give us money.Money is not easy to earn.
I give you some advice.You can buy a flower or a greeting card to your mother to show our best wishes.
yours
Ann
