If I smile at everyone I see today, how many of them will think I'm a simpleton. How many will think I'm drunk, or mentally deficient, or a dirty old man? How many simply won't notice?

Are there fixed percentages or does it depend upon the smile, or the individual receiving it? Will the perception improve if the individuals already know me, or does that depend on if they like me or not?

Or should I just not bother, and frown - as usual......
