You buy a bouquet of flowers and just walk down the street with them. At some point, inevitably, an older lady is going to jokingly say, “Oh, are those for me?” You immediately respond with, “Oh, yeah, there you are. I’ve been looking all over for you. Here you go.” You hand them the flowers and you walk away. To that lady, you are now the coolest person in the world.
The best time of year to do this is around Valentine’s day because it’s a bit more sentimental for everyone. Be careful, though. This is when florists jack up the price of roses.
