Army Staff Sgt. Yasmin Jefferson is back home after being away on active duty for the past couple of months, which is never an easy time, especially for her young daughters.So she decided to surprise Mikayla, 8, and Tatiana, 6, Wednesday at Sunset Lakes Elementary School.”I always think about how they are doing. We talk on Skype and I always reassure them that everything is just fine,” Jefferson.Both girls were paired up for a reading exercise and had no idea what was going on when their mom walked in.But when they saw their mother their eyes lit up and the tears started flowing. Mikayla’s teacher, Holly Morales, got emotional too.Morales grew up in the military and knows what it’s like to have a parent away.
