Hello guys, I just have a question. I'm not sure which sentence is correct. Thanks in advance. He can figure out things very quickly. or He can figure things out very quickly.

I think one of the best things that my mom did right in raising me is she taught me patience and discipline, especially in finances. I remember my mom had a small convenience store before and she would sometimes ask me to run it if she has other things to do. She would teach me strategies on how to manage it and give me tips on how to sell a particular product. At first I didn't like it because it was a lot of hard work, doing this stuff was already a lot of hard work for me because I was still in middle school back then. It was also very time consuming because I would be at the store for 3 or 4 hours almost every day, and because of it I didn't often had the time to hangout with my friends, and even if I could still hangout with my friends I was already too tired from that work and couldn't enjoy spending time with them anymore. The thing that I hated most about that job was to deal with drunk customers and people who often borrow money, arguing with those kind of people was really a pain in the butt! I almost even got into a fight once because I refused to loan a bottle of wine to a drunkard man.😄 At first I thought that my mom was doing this to me as a punishment for not doing good at school, but what I didn't know is that she was teaching me to be patient, wise, firm and disciplined, and how to handle finances properly. Because of it I'm forever grateful to my mom.

Hi guys, I just have a simple question. What does the sentence "Look who's laughing now" mean? Is this some kind of a revenge? Thank you so much for the reply.
