Ask your parents to do something about them. And also ask if they sent them.

I mean, I hope you're being nice to them. It may have ruined your plans for the week but they won't be around forever.

forget the other fun part but still invite you boyfriend over to hang out I know they want to see him

I smell a setup. Your parents probably asked them to keep an eye on you and make sure you and your boyfriend sleep in your own beds while they're gone. ;)

Two things. One: it sounds like you're a little too young for sex while your parents are away, and two: you will have a whole life with a man, but your grandparents won't be around too much longer. Get to know them and their lives before you lose them, you'll be happy you did.

The way my family did it was: you're not supposed to have anyone who isn't family into your family home when you're there alone or the rest of the family has gone away- even if it's someone you know. Mainly because if something happens, they won't be there to help and because the house is for the family only. Be grateful your grandparents give a shit about you and made an effort to keep you company. Anyone can find a root, but good family members are rare.

Lol that's sucks. I bet it was planned by your parents.

Best birth control ever.

Last year my 18 year old boyfriend's parents left for a beach trip and the same day his grandmother showed up. His mom said it was the grandmother's idea and she wanted to surprise him. Super close families have no boundaries, ever. They look at grandma coming into town while the parents are gone as a good thing. I looked at it as his overbearing mom didn't like me.

Maybe your parents called them because they knew they can't trust you
