“Let’s plan a baby shower”… how about no

So 3 girls at my job are pregnant . I’m a senior tech so responsible for one or two extra things, another coworker comes up to me and is like let’s plan a baby shower

I said yes, just cause I don’t want word to get around if I said no and don’t want to be judged for not being interested. I really have no interest though, I’m sure those women have friends and families of their own to throw baby showers; they don’t need a mini one at work. I’m not close with any of them I just want to do this job and go home

I’ll chip in for a gift,sign a card, or something but don’t want to help plan anything or sit around hearing more about babies

Does that sound heartless?
