I was texting this guy for a while and the texts always got NSFW (I'm pretty sure it's all he wanted from me) and one day he was asking me what I was up to and I said I was babysitting my baby cousin with my grandparents (who was around one at the time) and he said cool and the conversation stopped.
Few hours later my mum comes home from work and so does my uncle, but I'm still babysitting when they guy texts me again. He wants things to get NSFW. I tell him I can't because I'm holding a baby. He says it's fine because babies can't read.
I honestly thought "I can't sext because I'm holding a baby on my lap right now" was a pretty good reason but apparently not
