Hey! Mother's Day is coming. Have you planned something good for your mom? If not, try one of these tips.
　　What's Her Favorite?
　　Most teens don't know what their mom's favorite is. You do? Then, what are you waiting for? Buy her something she likes and wrap it carefully. The best time to give her that is while she is sleeping at night. Put it on the drawer next to her so that when she wakes up she'll be surprised to see it.
　　Treat a Queen
　　Your house is a palace with a king and queen (it doesn't matter if you're rich or poor). Our mother is the real queen in our life and in our family though her duties make her look like she is not. Give the lady a day off and you can do the housework.
　　Because of stress and the problems that she is facing right now, she doesn't look good any more. Perhaps you could take some of your savings to treat her in a salon or the department store. Then, choose nice clothes that would make her look beautiful!
　　Have Some of Your Time
Our mothers have special memories in mind. It is the time that they gave birth to their healthy baby. How about you? What's your best moment with her? Have you ever had a good time with your mother not talking about your problems and arguments? Have you ever told her how much you thank her for the life she gave to you, the time she cared for you? Maybe you can tell her how happy you are when she was there looking after you during your painful days in your life.
Tell the magic words
Life is short. We don't know what will happen tomorrow. Those three words can make her heart jump for joy, you know? Just tell her “I love you!” and it would make her smile so sweetly. Just try! We don't want to miss a thing, right?
