Often at the streets I see couples kissing, and I always try to stare at them closely while they do it, I never minded to do so but, why kissing couples always ask me "Do You Mind"?
They are saying to you "do you mind" because your invading there private space - what part of that don't you get ?
while couples are kissing on the street , you are very close to them and your watching them ? You have alot to learn about social etiquette , alot to learn.
Where I come from, if you stood to close to a couple watching them kiss , you would be given one warning to leave immediately , otherwise they might punch you in the face.
Seriously, go find yourself your own girlfriend to kiss.
