When I've met up with witnesses frm my old cong, they all comment how well I look. I make a point of being all smiles when I greet them, and I'm sure it confuses them to no end. ("why would she be so happy? Maybe she's got a boyfriend? Hmm, I didn't see anyone with her. Maybe she's become materialistic, yeah, that's it. She's driving a very nice car these days...")
As the saying goes: Smile. It makes people wonder what you've been up to...
