Leave the door open , mosquito coil, smells like Grandma's house
When it gets summer, I always use mosquito coils. One is out at the entrance hall, and tolet the wind get in, I always leave the door open.
When elementary school students come, they always say " it smells like my grandma's house".
Nowadays, they live a modern house, or apartment house. So they seldom leave the door open and they also use air conditioner, so they usually keep the windows closed. So they seldom ever use these coils because they are too smokey.
And actually, now I am a real grandmother.
