Pull your boss aside and say, "Boss, I wanted to let you know that I'm getting braces, and I'll have several dental appointments over the next few months. The first one is Thursday <insert date here>. I'm having several teeth extracted during that appointment, so I'll be out Thursday and Friday. I should be back that next Monday."
Don't offer to work from home ... your boss will take you up on your offer, and you may not feel up to fulfilling said offer. Take the Friday for yourself ... even if you wake up that Friday morning feeling ten feet tall and bulletproof, use that energy for yourself.
The trouble is...there are a few things that *have* to be done before she’s out, and one of them happens to be on the 12th.
I’m really hoping I can get in on the 4th, but we’ll see! That would be the best case scenario.
