Humor for the AM in a less than ideal situation

My mother has been up all night with my grandmother who needs emergency surgery. Naturally, being in grad school I said "welcome to my world" and "I bet this is bringing back memories for you." Her response was "never pulled an all-nighter in grad school because I always had two kids to get up and out to school in the morning." Touche. Well-played, I know where I stand now.
