But imagine this - son goes to a chalet party and stay overnight. At bed time, he takes out his socks and put them on. I am betting most young people don't wear socks at bed time? And I imagine some boys would go,"eh tofu, why you wear socks?! Still baby ar?" and then I wonder if his little gf would go,"aiyo tofu, so gu niang leh! Wear socks?!"
If tofu boy goes,"my mummy says wear socks at bedtime is good.", I am quite confident my son ain't gonna get a wife.
Who knows? If he is charismatic enough, he might actually convert everyone at the party to wear socks to sleep
