Input: Text: i travel often, such that i don't want to bring my expensive $40 electric tooth brush with me when i'm only staying 2 nights with my so. they live in another state so i'll come for weekends, they'll come visit too, etc. so a  2 night stay? i bought one of those [old fashioned tooth brushes](http://www.deltadentaliablog.com/wp-content/uploads/2013/09/10.22-get-to-know-your-toothbrush.jpg) that look like this. nothing happens, i use my oldie toothbrush for several days until, the morning i leave, i sense something is off. i asked my so why my toothbrush tastes bad and why i feel i have a sore throat coming on. she asks which is my toothbrush and when i show her my oldie brush, to which she denied that was my brush, saying that she uses that brush to clean the grout around the toilet. she apparently uses the same exact old type of brush to clean the grout on her tiled floor. here comes strep throat for me.
