It is interesting how so few know about this, since this is a personal practice I always did. It wasn't until I took my parents down for a trip down to Santa Cruz a while back seeing some other towns south of San Jose, that an older guy (native and apparantly a sailor from way back) noticed I did this for my mother.
He was like you are the first "young" man that I have seen that you have done this. My mom was confused and then he explained it ...
