May I wear a short-sleeved knit dress in black, provided it covers to the knee, with open-toed black heels?

I'm sure that would be the theme of the ball, but you don't necessarily have to.

It might be jammed. Check under the Roomba to see if anything is clogging the outlet.

Settings are still being moved from the Control Panel to the Settings app. Microsoft is focusing on moving other more general settings first.

A dressy shirt and heels are great, but jeans are a bit too causal for a formal event. Perhaps you could wear a skirt or leggings.

In case of accidents on board the airplane. You can easily escape the airplane.

The recipe here is using Chinese use black soybeans, which aren't the same as black turtle beans we use here for Mexican food.

If your hair is very fine, cutting it short may restore a natural curl, as length can pull it straight. Thinning shouldn't affect curl.

You can, but that is an unprofessional approach. It can also be disputed that it was not received.

That is a great decision. Just make sure that the dress is not too short, and make sure you can walk in the heels.

Use makeup to cover the scar, or put on knee-length leg warmers. I would suggest putting natural oils and moisturizer on the scar to help make the scar less visible....
