Well... I'm not gonna say it was personal experience (nor gonna deny it), but sometimes a guy is just dumb and not know how to act.
There's this one guy who have a hobby of baking. The girl he was seeing at the time (not dating yet) know this and, albeit she never bakes, think she'll bake something for him for Valentines to impress him.
The guy kinda knew it from how the girl tried to glean from him what to bake. He decided to bake the exact same thing for her on Valentines.
That would impress her, right? ...Right?
Imagine how awkward it was when she gave him her beginner's muffin and he took out the same kind of muffin, but hobbyist level to gave back to her...
