Erm, whenever I don't feel like riding? Like 99.9% of people that use this site, cycling in it's various forms is what I do as a hobby, I don't get paid to do it, so I'm under no pressure whatsoever to go cycling. So, sometimes when I've planned to go for a ride, and in the morning the weather's shite, i just shrug my shoulders sometimes, and play with the kids or on my guitar, I feel no compunction (or guilt for that matter) to boast that I'll MTFU and go out regardless of the conditions, as some folk on site's like this feel the need to do… No one's impressed, OK?
