Pissed, pissed, pissed-off

This icon doesn't express my wrath as well as The Eye of Shiv, but the sentiments are there.
I got an sms from Alexandra, asking me whether I will look after the "new" cat over the weekend.
I'm so incredibly, unutterably and totally pissed-off that I'm not going to answer it before I've calmed down, because I might say things I'd regret later (not for content, but for form).
But I'm going to say no, I swear I will. Because I effing don't want to feel bad again about spending too little time with the poor creature, while at the same time spending less with the Unholy Trinity. Why can't that stupid bint finally *understand*????? If that's her brand of friendship, I really don't need it. So the answer will be polite, but quite unequivocal: 1) didn't I express myself quite clearly on that issue in my last mail? 2) If you think you have to "save" animals, by all means do so, but don't count on my help. 3) Saving an animal means a little more than locking it in a small flat and having others give it food and water.
I know she's going to ask Irene after I refuse -- and this without even a thank you for the weekend before last -- and Irene is probably going to say yes. Not my problem.
Hell, I'm so fucking angry I barely resist the temptation to call her right away.
