LMAO, Cinta! If collecting bottles you don't drink is a drinking problem, I guess you have a pretty serious one!
Audrey, my Lithops have only bloomed once, (the pic I put in the general Lithops entry.) That bloom was in 2013 & haven't seen another since. From what I saw and have heard from others' anecdotes, the blooms open for several days, during the daytime, closing at night and opening again in the AM, until they're tuckered out after a few days. It would be perfectly reasonable to want to take them to work or on errands, everyone here would totally understand, but practical? IDK... can't wait to see what yours does! :+)
