Guilt Tripping

I hate it when people try to guilt me into doing something with them. Do they think that'll make me want to do it? If anything it'll make me more likely to NOT want to do it. And if they force me along it'll just make me sulky and irritated, if not flat out angry. I wish they'd understand that it's not that I don't want to spend time with them (usually)it's that I don't want to do what ever they're trying to make me do for whatever reason. Like when my grandmother woke me up at eleven to say she and my grandfather were taking me to a teahouse at noon. I had no clean cloths, was barely awake, and had planned to spend the day doing nothing. But instead of respecting me when I said that I had no clean cloths, didn't get much sleep(I lied a bit for that), and had planned to do nothing for the first day of spring break, she tried to guild me into going with them. Which not only ticked me off, but also made me even more guilty than I already was. Ugggggggggggggg why do people have t9o be so complicated?????
