Day-Maker #47

The most adorable small child ran through the student center, past our study cluster.  She wore a shirt that read, "Little Sis."  Ten seconds later, the second most adorable small child ran after her, wearing a shirt saying, "Big Sis."  Guess who got distract from their studies for the next 10 minutes?  If you guessed all 3 of us, males and females, you would be correct.
