Back to school. Somerville's public schools began the academic year last week. Tufts University is back in session. 

Even for people who haven't been in a classroom for years, the beginning of the school year can elicit thoughts of new beginnings. For others, it causes anxiety about homework, expenses and showing up to math class without clothes.

Back-to-school season is an important time of year, and we asked people on the street what this time of year means to them.
