Mama taught me manners

When you stay at someone's home as a guest you should do the following:

1. Offer to help with any chores possible, such as cleaning the kitchen, helping make dinner, keeping your aura and chatchkes to a minimum.
2. Leave your room clean enough so that anyone may enter because you never know what your host/s might need in it. This means making your bed everyday; sorry.
3. Offer to pay for things that your host/s purchase/s at the grocery store that are entirely for you, even if your host has every intention of telling you, "Don't be ridiculous." It's a nice gesture at the very least.
4. Take up minimal time on your host's computer, as s/he might need it for a reason or might be under time constraints of which you are not aware. Particularly if you are visiting from a place that is six time zones away, it's likely your host needs the computer more urgently than you.
5. Clean up the shower if you left hair or foamy soap scum in it. Gross.
6. Finally, don't be a burden. If you know you're going to get in the way, stay out of it. Really.

All other niceties are appreciated but I'd say these are some general rules to obey.
