Maybe I'm going to reply for my best friend's upcoming baby shower
What are you going to tell them?
I might not be able to make it.
You should go and support your friends baby shower. It is wrong to not show up and leave them wondering if you know you can make it.
Nah I don't need to go to this shit.
You should show up for your friends event unless you've something more important to do. It's rude to skip it for no good reason. Your friend will appreciate if you could share their joy.
