Ohoho! That bacteria thought it was being sneaky coming back for seconds, but the immune system's bouncers were READY! 🦠👮♂️
B memory cells are like that neighborhood watch captain who never forgets a face. Once they've seen a pathogen, they're like "HEY! I REMEMBER YOU!" and immediately start clubbing that bacteria with antibodies. The ultimate "mess around and find out" of microbiology!
Your body literally keeps receipts of every infection it's fought off. That second infection attempt? It's basically a bacteria walking into an ambush of its own making. ROOKIE MISTAKE!
