I just noticed I tend to use "but" and 'however" in almost every paragraph.
Examples (all of them are from the same story):
I almost let everything out. But, funny, I didn't. I didn't want him to feel bad. Which made me wonder if maybe I enjoyed punishing myself. But what for?
This was the first time we were going to be apart for so long. Two months wasn't a big deal for most people. But for me, it was an endless torture. But as I stood there, watching the bus disappear down the street, I reminded myself that it wasn't so bad. That we would still see each other on weekends.
Li was holding me from behind. I liked to sit like that—feeling his warmth on my back, and his moist breath on my neck. It made me feel protected, at ease. As though nothing in the world could hurt me. However, that day, something disturbed that feeling.
I wanted to cry. I wanted to shout at him, tell him that I was already here. However, I knew I couldn't protest. It was my fault, after all. I had come too early, and he probably thought I was still in Nantou.
Is their use justifiable? Or should I use something else instead?
