reminisce with (one) (about someone or something)
To spend time with one thinking back on and sharing memories (of someone or something), especially in a fond and sentimental manner. I spent the whole night reminiscing with Andrew about our times together in college. If you two are finished reminiscing with one , it's high time we got some work done!
reminisce with someone
to share memories with someone. I love to reminisce with my sister about old times. Todd was reminiscing with Alice about the good old days.
