Sometimes I don't blog for several days either. Sometimes I just don't have the time or the desire to do so. That's why I don't have a problem with not blogging for a longer period of time. It means there are things that are more important to me or that I enjoy more. So don't be so hard on yourself. :)
In any case, I wish you a wonderful and relaxing vacation. Japan is still on my list, so I'm excited to hear what you will report about it!
Thank you!
