What's the most memorable thing your kids have done for you?

Whenever he sees flowers, he would pick at least one and give it to me saying "For you Nanay, I love you". It doesn't matter if its wildflowers or santan or a gumamela, it's just so sweet. There was even this one time when he picked santan at church and I forgot to bring it with me, he cried and cried that we had to go back for him to get more and he made me promise never to leave my flowers again.
