Why do people freak out over a little cold?

My friend told me she may not be able to hang this weekend because she could a cold but it isn’t too bad. She told me she might have caught something from her cruise trip. I mean you can’t stay home or flake out on plans just because of a little cough. I told her, “Oh come on! You asked if we wanted to hang out this weekend if you don’t get sick. I said yes. People freak out on a little cold and stay home. Suck it up. Just let me know how you feel.”
She said her throat is starting to hurt and her cough won’t go away.
I haven’t seen her in a month. I miss her. I understand if she’s sick but you can’t stay home over a little cough.
Do you think I’m being insensitive.
