Would anyone else feel offended, I feel like I took it too personal but didn’t show it?

So, I started a new job… there was a celebration for someone. I went in while they were decorating and putting up the gifts for this work mate. I said what’s going on. And they said they totally forgot to include me but, I could come. Later on, someone asked me if I had gotten cake from the celebration. I went in there and told the guy happy birthday celebration. My colleagues all turned around , I didn’t see the cake and they didn’t offer. I stood there a minute and they didn’t say anything … so, I went to go wash my hands figuring out how to get away from the embarrassment and as I was walking out I said hey hey happy happy birthday again.
and left and went to do my work. I was embarrassed , I think the most. How would anyone else have handled it
