Well, if the mucous is clear, then the hankerchief works pretty well. This reminds me of the times when I'm taking a test and have only 1 tissue to wipe my runny nose with. Sometimes, the tissue gets too soaked and I have to wipe my nose with my hand and wipe the mucous on my pants. Good thing everyone is busy taking a test.
But, if the mucous is all brown and whatever funky colored, using a hankerchief would be gross.
