Mostly, because Barbara is spending the next four months in Glasgow, working on her Ph.D thesis.
Even though I'm only working ~20h per week (or try to, but now that we (maros, koki & me) own our own company it's more than 20h more often than not, but as I enjoy working with them, it's not much of a problem...), I won't have much time for non-work Perl stuff, because the whole household thing (incl. looking after one kid and one teenager) now rests on my shoulders. Up until now we split all of the work 50/50, so other than a lot of other men I'm used to do all of this, but doing it alone will be a little bit more demanding. But hey, it's only 4 months...
The only real downside is that I won't be able to travel, and thus will miss a lot of nice Perl events ...
