I saw a jumping spider while I was brushing my teeth, and I jumped back and she kinda cautiously prepared to run, so I said "Oh no I’m sorry lil spider I didn’t mean to scare you! You keep doing your thing, buddy! And she relaxed and then moved under the sink so I wouldn’t accidentally squish her while I brushed

I thought nothing of it until I saw her on my way the next day, and I said “Hi!” And waved, and she waved back lol

She waved back every time I saw her so I am pretty sure I made a friend/familiar
