SUICIDES
P.S. “Suicides” are “a run comprising a series of sprints of increasing lengths” (thank you yourdictionary.com), so named for the feeling that you will die from lung exhaustion and/or muscle collapse as a result. I am, therefore, referring to the mother on this one, not to the children. Thought I should clarify before some angry comments rolled in. Should “suicides” be called something else? Probably. Go try some and tell me what other word comes to mind.
