This is a sweet little piece. I have a few comments, though. Looking well, In English, usually means looking in good health. To look attractive is to look good, or to be good looking. Similarly, "how pleasantly they smell" is also a little tricky. Like "well" above, the use of the adverb form here ("pleasantly") is probably what you've been advised to do, but is not really what people would say or write. In this special case of personal description, it would be more normal to use an adjective, so "you smell pleasant" (or sweet, or whatever). The adverb form would be normal, though, if it is being used to qualify a following adjective - “you smell pleasantly fruity". Strictly, though, commenting on people's smell isn't that common, and would have to be handled with care to avoid rudeness. Although you have a number of instances of "they", you can't really drop the last one: you still need "and how contagiously they laugh." A purist or pedant might well object to your joining together three "Sometimes" sentences with commas, and would expect a full stop after each of your instances of "themselves", and a capital letter to follow.

ok tell me something[emoji]
