Because the back of my hand was hurt by sharp glass, I was looking for sticking plaster. But, I couldn't find it.
Then, I came up with going to a nurse's room. I thought it would be better to let my hurt hand healed by a lady for free than to buy sticking plaster from an elderly saleswoman.
Actually, I went there and got my hand healed. In addition to it, a nurse gave me spare sticking plaster.
What a kind lady she is!
I thought my choice was right.
