I am not sure about meaning of “how” in the below conversation. (English is my second language so I can’t understand details)
Someone: Do you remember we invited people to our house last month?
Me: Of course. That was so fun.
Someone: And you remember {how} Alice and John brought over their kids?
When I saw this sentence I thought it is more appropriate to use ‘that’ at the position of ‘how’. Because I just said about that experience Alice and John came with their kids. Is that different if I use ‘that’ in place of ‘how’ this case? And how is the meaning changed if I use ‘how’ instead of ‘that’?
Thank you for your help.
