TBBT is not mine.
It's a Double Drabble. Please forgive me for any mistakes in my English not very good. But I hope you enjoy!
It was very easy to find when Dr. Sheldon Lee Cooper was in love.
He started to get distracted. Don't monopolize the conversation in the university cafeteria, or in the apartment, car, anywhere. He spent much time looking nowhere in particular with an expression half fearful and unbelieving. Began asking questions about love and relationships. Do not complain when Leonard forgot his food order and not say anything about his career failure.
It was also easier to discover by whom Dr. Sheldon Lee Cooper was in love.
He smiled at her the whole time (not the smile to kill Batman, but a genuine smile). His cheeks were stained when she was near him. He began to allow her to touch him. He even allowed her to sit in his place for two and a half minutes!
And one day he invited her to go on a date.
They went to a restaurant (an acceptable of course, where no one would touch the food of Sheldon). He came back with glowing blue eyes, babbling about a kiss.
Dr. Lee Sheldon Cooper, PhD, was in love with the actress-waitress Penny.
End.
