Do I have a right to be angry?

Samm

So I’m 38+3 weeks. And my sister brought over a nasty ass cold yesterday getting my husband terribly sick. Fever and everything today. Do I have every right to be angry at her for even bothering to come over knowing I’ll be in labor any day now??? Plus I have an 11 month old as well. He’s just getting over something we’ve been trying to get out of the house for a week. I’m just livid because you’d think it would be common sense and a respect thing.
