Thailand

I think that Thailand is a special country. because I went there the year before last or "two years ago" and I fell in love with it. Although I only stayed for five days, it takes me some deep impression the experience affected me deeply and I took back some great memories with me. During the day, it's like an angel, but at night it's like a devil. I am not sure what you meant to say here. Do you mean that  Thailand at night is a stark contrast to Thailand during the day? For instance, perhaps at night there is more crime or something? I hope I'll have a chance to visit Thailand again.

I have never been to Thailand but I have seen many photos and videos and it is definitely on my list of places to eventually see and visit. :)

Thailand

I think that Thailand is a special country because I visited there two years ago(?) the year before last. Though, I was there for five days; it gave me some deep impressions. During the daytime, the vibe felt like an angel. But at night, it's gets a devil. I hope I'll have chance to visit there.
