Yeah hugs is good
I still hold my Mum's hand now, when we are together (I'm 23!!!) We were out in the supermarket one day, holding hands, like you do, I think I was about 18-ish and this woman tutted at us. So I threw my arms around my Mum and yelled, "I love you Mummy!"
We also cuddled in the biscuit aisle - strange supermarket hug related story! I think I hugged her once and she asked why, and I said, "'Cos we're in the biscuit aisle..." Good a reason as any I suppose...
So then we often hugged in the biscuit aisle!!!
