There's a way.

After sending my children to their calligraphy class, I dropped at a neaby coffee shop with an English textbook. I needed to wait for them for almost two hours, but I didn't mind at all: it meant I could enjoyed myself studying English over some coffee. I thought, however, I couldn't spend two hours there with just a cup of coffee. so I ordered a piece of bread and took a seat. I might have gained something useful from my textbook, but I must admit I surely gained weight by eating extra breakfast...
