I'm doing something creative for a competition at the moment which takes a number of hours to do. I was telling some people at work and they said "oh really that's good, I don't have time to do things like that.." in a rather superior tone.
It sounds so condescending as though I must have such an empty life that I have time to do extra things like that. I have kids and a job and do all the usual running around with s family etc so it's not as though I'm sat doing nothing all day.
I often hear this phrase a lot though which is fine because I know people have full lives but I'm sure they do things I "don't " have time for too.
Or people say it when what they really mean is they don't have the inclination/don't want to do it/ it's not a priority etc.
One colleague goes to the gym for instance but I don't say to her "oh I don't have time for that, I do have time it's just I can't be bothered! 
So I wish people wouldn't act superior about what they don't have time for! People seem to find time to use Facebook/Twitter/Mumsnet/meds about online which is fine, but I wish they wouldn't make me feel like I must have f all to do in my life other than a creative project for a competition!
