GRAMMAR AND EXPLANATION:
"Any" and "some" with singular countable nouns

When we use the word "any" in front of a singular countable noun. it means its not important which. For example. the sentence "Take any biscuit you like'' means that it isn't important which biscuit you take; you can choose whichever one you like.

When we use "some" in front of a singular countable noun, we are referring to a particular person or thing, but we don't know (or we don't want to say) who it is or which it is. For example, in the sentence "Some man came to see you this morning while you were out". we are referring to a particular man. but we can't remember or don't know who it was. 

When there's a thunderstorm, we first see the flash of lightning. Then, after a few seconds, we hear the thunder, even though the thunder and lightning actually happen at the same time. The reason for the delay in hearing the thunder is that sound travels more slowly than light.
