I snort when I laugh too much and that drives my daughter insane. Also, I can't stand doors being open so I am constantly closing them and that annoys people who are coming in and out. My attention also drifts so occasionally I have to ask people to repeat what they've said to me - that drives my students round the twist because they tink I'm not interested in what they have to say.
I love to annoy my kids. They are so easy to annoy.. almost everything I do annoy them. Like showing up in their apartment unannounced, dancing a la Elaine in Seinfeld until they scream "Mom, stop it!!!" , asking them when they are cleaning their apartment when I know the answer is never... I ask anyway. lol
