Yes, Tip is very smart...and kind as well. Since she knew I was very worried that one week and she tried to help me calm down...even though she still is not fluent in English. She handled it very well for me and for you. I will always be thankful to her for her good heart, professionalism and caring attitude toward me and you. So be kind to your sister as she helps you a lot, even with opening your bottle waters and fixing your watch.
