Answer 2

It seems like you are providing a conversation exchange between multiple individuals. Based on the conversation, it appears that Tom is unable to join Bev for a barbecue at her house on Saturday because he is helping his dad with gardening. Bev expresses disappointment that Tom cannot make it and suggests that maybe he can join another time. Bev also extends an invitation to Tom, asking if he would like to join them.

Since this is a conversation, I'll generate a response as if I were Tom:

Tom: Thank you for the invitation, Bev! I would love to join you and your friends for a barbecue at your house. However, I have already committed to helping my dad with the gardening on Saturday. I apologize for not being able to make it this time, but I would definitely be interested in joining you another time. Please keep me in the loop for future gatherings. Have a great time at the barbecue!
