Funny story!?

Last week when we had some guests here, we noticed water dripping from our bathroom door jam downstairs.  We realized someone was taking a shower upstairs and something was leaking!  Ack! Went and got buckets and held our breath that the upstairs bathroom was not flooding.  Well no one came downstairs complaining so we figured it must be the drain.....and then the 2nd person took a shower...eek! More water!  Well you can imagine we did not sleep well that night trying to figure out what was going on....
No comments from the guests the next morning...so after they left we checked out the bathroom and shower, and could see no problems. Ran water down the drain and no issue...what the heck???  I then remembered that when I was cleaning the shower earlier in the week that there was a loose bit of grout and it pulled out as I was cleaning.  So I got out the caulking and gave the base a new bead of caulk.  When the guests checked in last night we had the buckets ready, and our fingers crossed, but when the shower ran, there was no problem at all!  Whew!  Disaster averted!  Guess my cleaning was just too aggressive!  Wouldn't my Mom laugh if she saw that statement?
