S/O thinks my mom didn’t want to come to the house

I just finished cosmetology school. My parents wanted to celebrate but with Christmas coming we decided to wait until after since I live with my S/O and his parents.

My mom wanted to drop off a little gift and a cake. She calls me to tell me there’s a issue with the house so she doesn’t want to leave it long and to see if we’ll meet her 5 minutes from my S/Os house.

I tell him and he’s willing to meet her but basically said “why doesn’t she wanna come to the house”

I convince her to meet us halfway because 5 min from my S/Os house isn’t very long and I agree that it makes it seem like she didn’t want to come.

My S/O thinks that’s weird to meet her halfway and just wants to go to my parents house to pick up everything. My mom advises not to because of the issue with the house she says it’s a “shit show” there and we end up meeting her.

Should I do anything/bring it up? I tried explaining but I’m not sure he fully understands. I don’t want him to think my mom didn’t want to come to drop it off.
