I've been off work sick for a few days with a virus. I went back to work today (WFH). Tonight my friend is having a book launch. There is a slim but not impossible chance that I might bump into my workmates there. Do you think it's acceptable for me to go? It would be sitting down to listen to a reading to support my friend so it's a very sedate night out. I'm just worried someone will see me and question why I'm there if I've been ill. I was working today though so maybe I'm overthinking things?
