Do not.
Send postcards when traveling?
Poetry in the moonlight was a dangerous thing.
Do, but not always.
Ration electricity at home in times of high demand?
Do not; it's not really applicable to me right now.
Clean a room a little bit at a time (instead of all at once)?
Poetry in the moonlight was a dangerous thing.
Do, especially as we still own a cat that is sometimes naughty, and everyone thinks I should be responsible for its behaviour.
Feed children's pets?
Do not - but I do feed the family's pets.
Go to the library on a regular basis?
Poetry in the moonlight was a dangerous thing.
Do not. On a regular basis, that is. I can check the catalogue online, to see if there is anything available I would like to read.
Celebrate Valentine's day?
Do not.
Was the dishes every night?
Poetry in the moonlight was a dangerous thing.
Do - keep dishes all clean (no dishwasher where I live in UK)
Sit in front of TV doing several other things at the same time?
There, shining in the sunrise, larger than they had seen him before, shaking his mane (for it had apparently grown again) stood Aslan himself.

Do, quite often. Especially when washing up during the commercial breaks.
Recycle water for the garden?
Do not.
Loan books out if someone wants to read one you own?
Poetry in the moonlight was a dangerous thing.
Do, if I have a very good reason to believe they will return borrowed books. We used to charge fines for people who did not return books on time, after all.
Return library books/videos/CD's etc on time?
Do.
Take an annual vacation?
Poetry in the moonlight was a dangerous thing.
Do not. Or not any more. I'm retired.

Do not.
Have family over for holidays or special occasions?
Poetry in the moonlight was a dangerous thing.
Do, and as a rule
Have family sleeping overnight on holidays and special occasions?
