& that means, he'll still be in your heart?

So yesterday I had a family picnic, with all my cousins.  We sat and ate, and played around at the park.  One of my cousins, he's older than me, has 3 daughters, and a wife.  He's going to Iraq, as a mercenary, for 7 months.  His youngest daughter is a year old, and his oldest is 4.  My cousin was explaining to me how he was telling his oldest about his trip so far away, for such a long time.  He had said that she already had an idea of what was to go on.  And she was telling him about her grandpa (his dad) who lives in Utah, and she said "You'll still be in my heart, like your dad lives so far away, and is still in your heart."  So, I teared up a little, this 4 year old girl, trying to deal with such a difficult thing, something I wouldn't even at my own age, wouldn't be able to handle.
