is it possible for one molecule of salicylic acid to form an ester with a second molecule of the same substance? Use equations and/or structures.

Please help, i am pretty sure it couldn't because of steric hindrance, however i am not sure how to explain this further and what equations/structures would be appropriate!

thank you!

See your post below. A note: just because I couldn't find it on google doesn't mean is doesn't exist. But I think it is improbable.
