i read some guides on wikihow and decided to try and make my office crush like me. I waited around her desk until she came by and offered to buy her a snack from the vending machine
she was like "oh sure ahaha" and so i went to it and got her a peanut butter cracker, i handed it to her and she said thanks. i was burning with embarrassment and after that i just left

What the fuck. I'm so stupid and awkward. I can't even face her again after this pathetic attempt

What do I do? Can anyone give me actionable advice?
