my son's wisdom

My son and I were discussing what it means to be a grown-up and what you get to do versus what you have to do.  I asked him if he would still give me hugs when he was a grown up.  He said of course he would because I would still be his Mom.  We decided that one hug a day would be a great thing to start the day with, so, he said he would give me one hug every day forever.  I love my hugs, they are wonderful but lately he's been adding something.  About a week ago he started giving me two hugs saying "because I didn't give you one tomorrow."  This is so sweet and I love him for it, but it made me think.  Why not give an extra hug for tomorrow?  You haven't given them one tomorrow and what if you can't, you don't know what tomorrow will bring, you may not get to give that hug tomorrow.  Too soon he will realize that he isn't saying what he thinks he's saying, I'm sure he's more worried about yesterday, but I will not tell him to stop because I like my hugs for today and tomorrow.
