this is sandra o'hare. she's in the air force and stationed in south korea.s supposed to last 12 months, but she's here early. she had help from the restaurant staff. they closed all the blinds so her family couldn't see her. here she comes. it was worth it because of this moment right here. she shows up and mom loses it. all of those emotions are bottled up and then just explode all at once. >> it's all love. >> looks like that's her sister there. they have the same reaction. >> that is her sister. her mom, sister, and two brothers. her dad happened to be in on it. they're trying to express their excitement. >> but can't. it's all stuck in your throat. >> she went through a lot to get home. she had a layover in the airport, had to stay overnight. they were all worth it for this reaction and response right here. >>> this next fella hasn't seen his mom in two years. he's in the navy. but on this day, again, nobody's going to see me. >> i wonder what the security people are thinking on this. he's sneaking around but holding flowers and smiling. >> mom's at work
