Generally at present it is 8.35 (for 8.30 departure).
Gah! The SS does this to me every market day. The evening before we set out and agree (note we *agree*) the time we need to leave the following morning. Every time, I stipulate that we need to be away *on time*. And every bloody morning we leave 5-10 minutes late while she faffs around looking for her handbag, specs, lipstick, mobile etc, etc.
It winds the f**K out of me. And then she has the audacity to ask me why I'm grumpy in the mornings.
6.30am is just that. Not 6.37am or 6.39am - it's 6 bloody 30!! I'm always up first and always ready to go on time, while her (admittedly gorgeous arse) remains stuck to the mattress for 7-9 minutes longer than it should. I'm happy and lovely and a delight to be around when we wake up. That 7-9 minutes will turn me into a steaming monster for the rest of the morning.
Why the hell does she insist on doing it?

Be warned - it's not just teenagers who do it!
