My sister once had a big bootied spider in her milk, and not only did it further my fears of spiders, but it also made me scared to drink milk for a while, as I always thought of a spider crawling into my mouth as I drank. But yeah maybe you should search for more bugs or smth, just in case. ^^
Ithink it qas probably chilling in the cup before i waterboarded it with milk. That's on me, I shoulda checked, but that means something in my cabinet is attracting these things. I should try to find out what.
And yes, I am scared to drink milk. I drank a fly accidentally before. Multiple times. It was not fun.
