I am currently studying in a high school, and I have several friends. Among them is a girl I like. We have several common interests e.g. gaming, and we're on very good terms and talk a bunch in real life and online. When I'm in a group, it's pretty easy to find topics to talk about; however, when I'm talking to her alone, there are often a few problems:
a) The conversation gets quite slow, and I run out of things to say. The silence gets quite awkward. b) If she makes small 'complaints', e.g. "I'm tired" or is happy about something trivial, I can't find anything to say to that. I sometimes end up just smiling awkwardly if the topic before was in some way funny.
Question: What can I do in the above situations? Where can I improve?
