My sister called me in a panic a couple weeks ago because Walgreens sent her notification that the ranitidine my nephew took around 4-6 months old was in the recalled lots or something. She didn't like my answer of 'he'll almost certainly be fine, nothing you can do'. She was like, "but what do I
do"...I kept telling her what is done is done, lots of things cause cancer (like the chewing tobacco my BIL uses?), call her pediatrician if it would make her feel better, etc. Eventually I got frustrated with her and told her if she wanted to do something she should get in a time machine and go back and take it out of his mouth and she hung up on me.

She was already spoiling for a fight though because my mom didn't answer her before she called me (twice), I didn't answer because my phone was dead (but in her mind I was
ignoring her of course), and then she had to call my dad to get him to take me his phone.
