My 4yr olds Questions

YES!!! Its the middle of the week and still so much to do .I went to Walmart yesterday and My 4 yr old daughter Kept asking me what all the heart balloon and candy were for. When I told her that next week is Valentines day she promptly ask "What was Valentines day?" LOL DO I give her the long or short version ?as I thought for a minute to think of a simple way to explain to her my 12 yr old son blurts out " ITS FOR LOVERS" (gasp) cuz I knew what was coming . "mommy what are lovers" Wow what do I say to that , after telling my son to shush. I explained to her that Valentines Day is a special day when people show there love to each other with gifts. To my surprise she said " that silly mommy you know I love you all the time and I don't have to get you anything" I know what I said to her was not the best explanation of Vday but her response was the best a mom could ask for !!! I love my kids!
