Am i wrong for forgetting a bridal shower?

Ill start off by saying in the 9 years ive been dating my husband and 1 year married ive met his fathers sister (husbands aunt) 3 times-that includes the rest of his fathers side also for the most part. Once at a funeral, for my own bridal shower, and wedding. I have worked 13 days straight due to short staff and 2 employees taking vacation together. The norm was/still is come this week 9-10hr days (2 days i worked 12hr shifts). I told my husbands aunt i couldnt attend her sons bridal shower because i had work. Yesterday my boss gave me the day off because she didnt realize i had worked that many days straight(she took my shift) so i was extremely excited to relax, hang out with my husband and enjoy some much needed time with him. I posted a picture of us on facebook out and about and i got a reply from his aunt saying, "We missed you at the shower." This really erked me because it seemed passive aggressive. Ive met the bride for 5 minutes at my wedding and ive seen his aunt 3x. How can you miss your nephews wife if you dont even have your nephews number or reach out to him ever? My days have been mooshed all over the place, i finally got a day off on short notice but genuinely forgot the shower. My brain was focused on sleeping in and spending time with my husband. He usually works week days/ weekends and i work morning shifts than night than morning so we never really see eachother. Am i over thinking this? I did send a gift because i was scheduled to work. I just think it was very snarky and not genuine. I did make a mistake by forgetting because my ass is exhausted but of coarse she wouldn't know because we dont talk 😒.
