There are two errors in the paragraph:
Grammatical Error: In the sentence "Just before it became too frustrating, I found them in the garage next too my hammer.", the phrase "next too" should be changed to "next to" for correct grammar. The correct sentence would be: "Just before it became too frustrating, I found them in the garage next to my hammer."
Logical Error: In the last sentence, "The funny thing about losing things is, you always find them in the last place you lock." the phrasing suggests that the lost item is found in the "last place you lock." However, this statement is not logically consistent with the rest of the paragraph. In the paragraph, the keys were found in the garage, not in a locked place. The correct statement should reflect the actual situation, for example: "The funny thing about losing things is, you never know where you'll find them."
