Men and their cars

A friend of mine is driving up from Italy this afternoon. ETA around 5pm. But guess what? At around 4.30 I get a phone call. "I might be a bit late, more around 6.30pm". s'fine. No problem. I was deep into second season of House anyway, and really comfortable on the sofa. So 6-ish I started to get dressed and get ready. Then another phone call. "I'm in Zug now, running a little late". Yeah, I'd say. Why is it that men always are time optimists? I'm fairly sure he wasn't gonna be alone on the road on a Saturday afternoon from Italy to Zürich. That road is always busy. I wonder if this is the same reason why they think 10cm is 20cm :)??
